As crypto trading automation accelerates into 2025, choosing the right API interface for your bot could be the critical difference between lagging behind or capitalizing on real-time opportunities. But when it comes to REST vs WebSocket crypto APIs, which technology should you select for power, reliability, and performance? This post details the core differences, essential trade-offs, and latest best practices for crypto API comparison, empowering you to make a technical, mission-aligned decision for your next-generation trading bot.

REST and WebSocket: Core Concepts for Crypto APIs

To understand which API protocol is optimal for your crypto bot in 2025, let’s clarify what REST and WebSocket actually do—especially in a high-frequency, automation-driven ecosystem.


     

     


The fundamental contrast: REST works in a "pull" model (request/response), while WebSockets operate in a "push" paradigm (real-time streams). This distinction plays a major role in how bots interact with exchanges and handle crypto market shifts.

Performance, Latency, and Reliability for Crypto Bots

Performance and data freshness are critical for crypto APIs in 2025. High-frequency or latency-sensitive trading bots depend on receiving accurate, instant data on price movements and order book changes.

       

Yet reliability considerations persist. WebSocket connections may experience drops, require reconnection logic, and occasionally miss events during high network volatility. REST, while slower, may provide more consistency under unstable conditions.

Scalability, Security, and Use Cases in Crypto API Comparison

Your crypto bot’s requirements—frequency of updates, types of orders, and compliance frameworks—may drive the API choice. Here’s how REST and WebSocket compare across scenarios relevant in 2025:


     

     


Security-wise, REST can offer granular access controls per endpoint. WebSockets, though encrypted, have unique session management and timeout considerations—especially important for bots managing real funds.

In the ever-evolving crypto automation landscape, developers and researchers are seeing:


     

     

     


Ultimately, the “better” API depends on your bot’s profile: Speed-critical, event-driven bots gravitate to WebSockets, while research bots or those trading on daily signals may remain with REST. Many leading bot frameworks in 2025 offer seamless switching or even run hybrid workflows for best-in-class resilience.

Practical Tips for Comparing REST vs WebSocket Crypto APIs

When evaluating crypto APIs for your bot or automation project, consider these practical criteria:

    Above all, test API performance in real-market scenarios—using sandboxes or historical replays—to ensure your bot’s architecture is future-proofed for 2025 volatility and growth.

    FAQ: REST vs WebSocket Crypto APIs for Bots in 2025

    What are the main differences between REST and WebSocket APIs?

    REST APIs use isolated request/response cycles and are suited for infrequent or simple queries. WebSocket APIs sustain continuous, two-way connections for real-time market data updates. The choice depends on whether your bot needs static or streaming data.

    Which API type is better for real-time crypto trading bots?

    WebSocket APIs are preferred for real-time trading bots due to their lower latency and ability to push instant data updates. However, implementation complexity and stability must be considered.

    Can I use both REST and WebSocket in the same bot?

    Yes. Many bots use REST for account management or trade execution and WebSocket for live data streams. This hybrid approach leverages the strengths of each protocol.

    Are there security differences between REST and WebSocket crypto APIs?

    Both protocols utilize SSL encryption and API key-based authentication, but WebSocket sessions require more careful management and regular re-authentication to prevent stale or hijacked connections.

    How do I choose the right API for my crypto bot?

    Assess your bot’s use case—speed versus reliability, frequency of queries, data intensity, and integration requirements. Testing both protocols with your trading logic is recommended for optimization.

    What’s the Best Time to Trade Cryptocurrency?

    Token Metrics Team
    8 min
    MIN

    Cryptocurrency trading is a 24/7 market—unlike stocks, there’s no opening or closing bell. This leads many traders to wonder: “When is the best time to trade cryptocurrency?”

    The truth is, timing your trades can make a huge difference in profitability. Trading during periods of high liquidity or increased volatility can provide better opportunities, while poorly timed trades can lead to slippage and losses.

    In this guide, we’ll explore the best times to trade crypto, how different time zones affect price movements, and how Token Metrics can help you identify the right moments to enter or exit trades using AI-powered insights.

    Why Timing Matters in Crypto Trading

    Even though the crypto market never sleeps, trading activity is not equal throughout the day.

    • High liquidity: When more traders are active, spreads are tighter, making it easier to enter and exit trades at good prices.
    • Volatility opportunities: Price swings create profit potential—but also risk.
    • Market overlaps: When multiple regions are active, volume surges.

    Knowing when the market is most active can help you reduce trading fees, minimize slippage, and maximize your gains.

    The Best Times to Trade Cryptocurrency

    1. Overlap Between U.S. and European Markets (1:00 PM – 5:00 PM UTC)

    The busiest period for crypto trading is when U.S. and European sessions overlap.

    • Why?

      • The U.S. is home to major crypto exchanges and institutional traders.
      • Europe contributes significant trading volume and liquidity.

    • Benefits:

      • Higher volatility for short-term traders.
      • Tighter spreads for efficient execution.

    This overlap often sees the biggest price movements of the day—perfect for day traders and scalpers.

    2. Early U.S. Trading Hours (12:00 PM – 3:00 PM UTC)

    The start of the U.S. session brings increased activity from institutional investors and retail traders waking up to market news.

    • Best for:

      • News-based trades (after U.S. economic announcements).
      • Entering/exiting positions with high liquidity.

    3. Weekend Volatility (Saturday & Sunday)

    Crypto is unique because weekend trading can be extremely volatile due to:

    • Lower liquidity (fewer institutional players).
    • Retail-driven price movements.

    • Who benefits:

      • Swing traders looking for sharp moves.
      • Those willing to tolerate higher risk for bigger gains.

    4. After Major News & Events

    The “best time” isn’t always about the clock—it’s about market catalysts.

    • Regulatory updates.
    • Exchange announcements.
    • Macro events (interest rate changes, economic data).

    These events can cause instant surges or drops—great for traders who react quickly.

    Does the Day of the Week Matter?

    Yes. Research shows:

    • Mondays & Fridays: Often more volatile as traders adjust positions before/after the weekend.
    • Midweek (Tuesday–Thursday): Tends to have steady, higher trading volumes.

    For swing traders, entering positions midweek may reduce erratic weekend exposure.

    This data-driven approach takes the guesswork out of timing.

    Final Thoughts

    So, what’s the best time to trade cryptocurrency?

    • Weekdays during the U.S.-EU overlap (1:00–5:00 PM UTC) offer the best liquidity and volatility.
    • Early U.S. hours and weekends can also present opportunities—but with higher risks.
    • Major news events often create the best entry/exit windows.

    But the truth is, there’s no universal “perfect time.” The real key is using data-driven insights to trade at your best time—when probabilities are in your favor.

    That’s why Token Metrics is essential for traders. With AI-powered trading signals, narrative tracking, and portfolio management tools, Token Metrics helps you time the market intelligently, not emotionally.

    How Do I Keep My Cryptocurrency Safe?

    Token Metrics Team
    8 min
    MIN

    The cryptocurrency market has created life-changing wealth for millions, but it has also attracted hackers, scammers, and bad actors. From exchange hacks to phishing scams and rug pulls, billions of dollars in crypto have been lost due to poor security practices.

    If you’re serious about trading or investing in crypto, one of your top priorities should be keeping your cryptocurrency safe. In this guide, we’ll walk through the biggest risks to your crypto security, best practices to protect your assets, and how Token Metrics can help you make informed, safe decisions when navigating the crypto market.

    Why Is Cryptocurrency Security So Important?

    Unlike a traditional bank account, cryptocurrency transactions are irreversible. If your funds are stolen, there’s usually no way to recover them.

    • No centralized authority: There’s no bank to call for refunds.
    • Pseudonymous transactions: It’s nearly impossible to trace funds once they’re moved.
    • High-value targets: Hackers actively target crypto investors due to the potential for large payoffs.

    This means you are your own bank—and you’re responsible for protecting your funds.

    Common Threats to Your Cryptocurrency

    Before learning how to protect your crypto, you need to know what you’re up against:

    1. Exchange Hacks

    Crypto exchanges are frequent targets for hackers. Even top-tier exchanges like Mt. Gox and FTX have experienced devastating losses.

    2. Phishing Attacks

    Scammers use fake websites, emails, or social media accounts to trick you into revealing your private keys or login credentials.

    3. Malware & Keyloggers

    Cybercriminals install malicious software on your devices to steal passwords and seed phrases.

    4. Rug Pulls & Scams

    Fraudulent projects lure investors with promises of high returns, then disappear with the funds.

    5. Human Error

    Lost passwords, mishandled private keys, or accidental transfers can lead to permanent loss of funds.

    How to Keep Your Cryptocurrency Safe

    Here’s a step-by-step approach to safeguarding your crypto:

    1. Use a Secure Wallet

    Hardware Wallets:

    • The safest option for long-term storage.
    • Devices like Ledger or Trezor keep your private keys offline, out of reach of hackers.

    Software Wallets:

    • Convenient for active trading but more vulnerable to attacks.
    • Use reputable wallets like MetaMask or Trust Wallet and enable strong security features.

    Pro Tip: Use a hardware wallet for long-term holdings and a software wallet for small, active trading balances.

    2. Enable Two-Factor Authentication (2FA)

    Always enable 2FA on your exchange accounts, wallets, and email addresses.

    • Use Google Authenticator or Authy, not SMS-based 2FA, which is susceptible to SIM swaps.

    3. Beware of Phishing & Fake Websites

    • Double-check URLs before logging into exchanges or wallets.
    • Never click links from suspicious emails or DMs.
    • Bookmark the official websites of your exchanges and platforms.

    4. Keep Your Seed Phrase Offline

    Your wallet’s seed phrase is the master key to your funds.

    • Write it down on paper and store it securely (safe, vault).
    • Avoid storing it in digital form (cloud storage, photos).
    • Consider splitting the phrase into parts and storing them in separate locations.

    5. Research Projects Before Investing

    Many scams and rug pulls target uninformed investors chasing hype.

    How Token Metrics Helps:

    • Use AI-powered Investor Grades to assess projects for long-term viability.
    • Leverage Moonshot Finder to discover vetted early-stage tokens with real growth potential—not scams.

    6. Diversify Your Storage

    Don’t keep all your crypto in one place.

    • Use multiple wallets for different purposes (trading vs. holding).
    • Spread funds across hardware, software, and exchange wallets.

    7. Stay Updated on Threats

    The crypto landscape changes fast.

    • Follow credible crypto news platforms.
    • Monitor regulatory updates and security alerts.
    • Use Token Metrics to stay ahead of market narratives and avoid projects flagged as high-risk.

    4. Narrative & Market Tracking

    Stay ahead of emerging narratives and security concerns with Token Metrics’ real-time AI-driven analysis, helping you dodge risky trends.

    Practical Security Checklist for Every Crypto Holder

    1. Use a hardware wallet for long-term holdings.
    2. Enable 2FA on all accounts—never rely on SMS-based security.
    3. Store seed phrases offline and securely.
    4. Avoid suspicious links and verify all URLs.
    5. Research every project using platforms like Token Metrics.
    6. Diversify storage across multiple wallets.
    7. Stay informed about new threats and market risks.

    Final Thoughts

    So, how do you keep your cryptocurrency safe? It comes down to strong storage practices, personal vigilance, and making informed investment decisions.

    While hardware wallets and 2FA secure your assets, knowing where to invest is just as important. That’s where Token Metrics comes in—using AI-powered analysis to help you avoid scams, choose safe projects, and trade with confidence.

    In crypto, you are your own bank—so take your security seriously. And with Token Metrics guiding your decisions, you can navigate this high-risk market safely and profitably.

    What Are Trading Fees and How Do They Work?

    Token Metrics Team
    8 min
    MIN

    If you’ve ever bought or sold cryptocurrency, you’ve likely noticed that exchanges charge trading fees. While these fees may seem small at first glance, they can add up significantly over time, especially for frequent traders.

    Understanding how trading fees work is essential for maximizing your profits and choosing the right platform and strategy. In this guide, we’ll explain what trading fees are, how they’re calculated, the different types of fees, and how Token Metrics can help you minimize costs while optimizing your trades.

    What Are Trading Fees?

    Trading fees are charges imposed by cryptocurrency exchanges whenever you execute a trade—whether you’re buying, selling, or swapping digital assets.

    • Purpose:

      • They compensate exchanges for providing liquidity, security, and order-matching services.
      • They discourage spam orders that could overload the exchange.

    Example:
    If you buy $1,000 worth of Bitcoin with a 0.1% trading fee, you’ll pay $1 in fees for that transaction.

    How Are Trading Fees Calculated?

    Most crypto exchanges calculate fees based on:

    1. Trade Value (Percentage):

      • The most common model.
      • Fees are a percentage of the total trade amount (e.g., 0.1% per trade).

    2. Flat Fees:

      • Some platforms charge a fixed fee per trade, regardless of trade size.

    3. Tiered Fee Structures:

      • Frequent traders often benefit from lower fees when they reach certain monthly trading volumes.

    Maker vs. Taker Fees

    Many exchanges use a maker-taker model to incentivize liquidity:

    • Maker Fees:

      • You pay a lower fee (or sometimes nothing) when you add liquidity by placing a limit order that isn’t immediately matched.

    • Taker Fees:

      • You pay a higher fee when you remove liquidity by placing a market order that is filled instantly.

    Example:
    On Binance, makers might pay 0.08%, while takers pay 0.1%.

    Types of Crypto Trading Fees

    When trading crypto, you’ll encounter more than just trading fees:

    1. Trading (Transaction) Fees

    • Charged when buying or selling crypto.
    • Often range from 0.05%–0.5% depending on the exchange.

    2. Deposit Fees

    • Some exchanges charge when funding accounts via credit card, PayPal, or bank transfers.
    • Crypto deposits are typically free.

    3. Withdrawal Fees

    • Charged when moving funds off the exchange.
    • Often fixed per withdrawal (e.g., 0.0005 BTC).

    4. Network (Gas) Fees

    • Separate from exchange fees, paid to blockchain validators.
    • Ethereum and other networks can have high gas fees during peak demand.

    Why Do Trading Fees Matter?

    Even small fees can significantly impact your profits, especially if you trade often.

    Example:

    • A day trader making 50 trades/month with a 0.1% fee per trade on $1,000 positions will pay $50/month in fees.
    • Over a year, that’s $600 lost to fees—before considering withdrawal or gas costs.

    This is why reducing fees is crucial for active traders.

    How to Minimize Trading Fees

    1. Use Low-Fee Exchanges

    Compare platforms—Binance, Bybit, and Kraken often offer competitive rates for high-volume traders.

    2. Increase Your Trading Volume

    Many exchanges lower fees as your monthly trading volume increases.

    3. Use Limit Orders

    Save on fees by acting as a maker instead of a taker whenever possible.

    4. Pay with Exchange Tokens

    Some exchanges offer discounts when fees are paid with their native token (e.g., BNB on Binance).

    5. Optimize Your Trading Strategy with AI

    Instead of making dozens of small trades, use data-driven insights from Token Metrics to make high-probability trades—reducing overall fee impact.

    How Token Metrics Helps You Save on Fees

    Token Metrics isn’t an exchange—it’s an AI-powered crypto research and trading platform designed to maximize your profits.

    Here’s how it helps with trading fees:

    1. AI-Powered Trade Optimization

    Token Metrics provides bullish/bearish trading signals based on 80+ technical indicators, helping you enter fewer but higher-quality trades—minimizing unnecessary fees.

    2. Trader & Investor Grades

    Our proprietary grading system helps you identify top-performing cryptos, reducing guesswork and avoiding costly trial-and-error trading.

    3. AI-Managed Indices

    Instead of manually rebalancing portfolios (and paying multiple trading fees), use Token Metrics AI-driven crypto indices, which rebalance intelligently while keeping transaction costs low.

    4. Narrative Tracking

    Our AI detects emerging crypto narratives early, helping you position yourself before the market gets crowded—reducing the need for excessive short-term trading.

    Practical Example: Using Token Metrics to Reduce Fees

    Imagine you’re trading altcoins manually and make 20 trades/month.

    • At 0.2% per trade on $1,000 positions, you pay $40/month in fees.
    • With Token Metrics AI signals, you cut this down to 8 high-probability trades per month—reducing your fees by 60% while increasing win rates.

    This is how data-driven trading saves both money and stress.

    Final Thoughts

    So, what are trading fees and how do they work? They’re the charges exchanges take for facilitating trades, withdrawals, and transactions—and while they may seem small, they can eat into your profits quickly.

    The good news? You can minimize trading fees with the right strategies—and Token Metrics can help.

    By providing AI-powered trading signals, long-term Investor Grades, and automated crypto indices, Token Metrics helps you reduce unnecessary trades, make smarter decisions, and maximize your returns—all while minimizing the impact of trading fees.
