Cryptocurrency Exchange 2018: Fees, Security, Liquidity, Features, and Selection Criteria

The cryptocurrency exchange landscape in 2018 was a vibrant but volatile ecosystem. This guide examines the key factors that defined the best platforms: fee structures, security practices, liquidity depth, asset coverage, custody solutions, compliance, and the criteria that helped users choose the right exchange for their needs.

📊 The 2018 Exchange Landscape

By 2018, the cryptocurrency market had evolved from its early experimental days into a maturing ecosystem with hundreds of exchanges competing for users. The landscape was broadly divided into three categories:

The year was marked by rapid growth, regulatory uncertainty, and significant security incidents. Understanding the characteristics of each exchange type was essential for users navigating the market.

💡 Historical Context

2018 was a year of both consolidation and fragmentation. While leading exchanges like Binance dominated the market, hundreds of smaller platforms vied for attention. The market crash in early 2018 tested the resilience of many exchanges, and several did not survive the subsequent bear market.

💰 Fees and Spreads

Fee structures were a primary differentiator between exchanges in 2018. Users compared platforms based on trading fees, deposit and withdrawal costs, and the spread between buy and sell prices.

Trading Fees: Maker vs. Taker

The maker-taker model was the industry standard. Makers (those adding liquidity to the order book) were incentivized with lower fees, often ranging from 0.05% to 0.15%. Takers (those removing liquidity) typically paid 0.10% to 0.25%. Some exchanges offered volume-based discounts, reducing fees for high-volume traders.

Native Token Discounts

A notable trend in 2018 was the use of native tokens for fee discounts. Binance led this approach with its BNB token, allowing users to reduce trading fees by 50% when paying in BNB. Other exchanges, including KuCoin and Huobi, adopted similar models.

Deposit and Withdrawal Fees

Spreads and Market Depth

The spread — the difference between the best bid and ask prices — reflected liquidity. Exchanges with high liquidity, such as Binance and Bitfinex, offered tighter spreads (often 0.1% or less), while smaller exchanges had wider spreads that increased trading costs.

⚠️ Important

Fee structures and spreads change over time. For the most current information, always verify on the exchange's official website and review their published fee schedule. Network fees for withdrawals also fluctuate with blockchain conditions.

🪙 Asset Coverage and Trading Pairs

The number and variety of cryptocurrencies listed on an exchange were a key consideration for users seeking exposure to diverse assets.

Major Assets

All major exchanges supported Bitcoin (BTC), Ethereum (ETH), and Tether (USDT). Most also offered Litecoin (LTC), Bitcoin Cash (BCH), and Ripple (XRP).

Altcoin Coverage

Altcoin selection varied greatly. Binance and Bittrex were known for their extensive altcoin listings, offering hundreds of trading pairs. Other platforms like Coinbase were more selective, listing only a curated set of assets.

Fiat Support

Users with a specific asset in mind had to verify its availability and the trading pairs offered before committing to a platform.

💧 Liquidity and Market Depth

Liquidity was a critical factor for traders, affecting execution quality, slippage, and the ability to enter or exit positions efficiently.

Understanding Liquidity

Liquidity refers to the market's ability to absorb buy and sell orders without causing significant price movements. In 2018, the top exchanges by trading volume (Binance, OKEx, Huobi, and Bitfinex) offered deep liquidity for major trading pairs. This meant tighter spreads and faster execution.

Order Book Depth

A deep order book had large orders at various price levels, reducing the risk of slippage. Users could check order book depth charts to assess whether an exchange could handle their trade size without significant price impact.

Wash Trading Concerns

In 2018, the industry faced significant scrutiny regarding fake trading volume (wash trading). Many exchanges reportedly inflated their volumes to attract users. The amount of actual, organic liquidity was often lower than reported, making due diligence essential.

🔹 High Liquidity Indicators

  • High 24-hour trading volume
  • Narrow bid-ask spreads
  • Large orders in the order book
  • Multiple active trading pairs
  • Fast order execution

🔸 Low Liquidity Indicators

  • Low or volatile volume
  • Wide spreads
  • Thin order book
  • Significant slippage on medium-sized orders
  • Large price swings on small trades

🛡️ Security and Custody Practices

Security was arguably the most critical factor for exchange selection in 2018. Several major hacks had shaken confidence in the industry, making robust security measures a top priority for users.

Cold Storage and Multi-Signature

Exchanges that stored the majority of user funds in cold storage (offline wallets) were considered more secure. Multi-signature wallets, which required multiple private keys to authorize a transaction, were the gold standard for custody.

Two-Factor Authentication (2FA)

Nearly all reputable exchanges required 2FA, and users were strongly advised to use Google Authenticator or hardware security keys rather than SMS-based 2FA, which was vulnerable to SIM-swapping attacks.

Withdrawal Whitelists

In 2018, many exchanges implemented withdrawal whitelists, allowing users to specify a set of addresses that could receive withdrawals. This added an extra layer of protection against unauthorized access.

Security Audits and Insurance

Notable 2018 Security Incidents

2018 saw several high-profile exchange hacks, including attacks on BitGrail and the Coincheck breach. These incidents underscored the importance of choosing platforms with proven security track records.

⚖️ Compliance and Regulatory Status

Regulatory compliance was becoming increasingly important in 2018, as governments worldwide began to formulate cryptocurrency regulations.

Licensing and Jurisdiction

KYC/AML Requirements

Geographic Restrictions

Geographic restrictions were common due to regulatory constraints. For example, US users were often restricted to platforms specifically licensed for US operations.

📌 Verification Practice

To verify an exchange's compliance status, check their website for licenses, regulatory partnerships, and the jurisdictions they serve. Always review the terms of service for geographic restrictions and KYC requirements before opening an account.

🖥️ Customer Support and Usability

User experience and customer support were significant differentiators in the competitive exchange market.

Customer Support Channels

User Interface and Experience

Educational Resources

Exchanges like Binance and Coinbase provided educational content, including guides, tutorials, and market analyses, helping users navigate the complex crypto landscape.

📘 A Practical Scenario

📌 Scenario: Choosing an Exchange in 2018

The Setup: You are a new user looking to buy Bitcoin (BTC) and a few altcoins. You have never used a cryptocurrency exchange before and are concerned about security and fees.

Evaluation Process:

  • Step 1: Define your needs. You plan to buy BTC, ETH, and a few high-cap altcoins. You need a platform with strong security and competitive fees.
  • Step 2: Research options. You review Binance, Coinbase, Kraken, and a DEX. You note that Binance offers the broadest altcoin selection and low fees but lacks fiat support.
  • Step 3: Assess security. You check each exchange's security practices: cold storage, 2FA, and past security incidents. Binance and Kraken have strong reputations, while smaller platforms raise concerns.
  • Step 4: Compare fees. You calculate the total cost, including trading fees and withdrawal fees. Binance offers the lowest fees, but you need to pay via crypto transfer.
  • Step 5: Test usability. You sign up for Binance and Kraken, complete the KYC process, and explore their interfaces. Binance's advanced features suit your trading plans, while Kraken is simpler for fiat deposits.

Outcome: You choose to use Binance for trading and Kraken for fiat deposits, with a hardware wallet to hold your funds securely.

This scenario highlights a multi-exchange strategy, using the strengths of different platforms to meet specific needs.

✅ Exchange Selection Checklist

Use this checklist when evaluating a cryptocurrency exchange for your needs.

  • Security track record: Investigate the exchange's history of security breaches and how they handled incidents.
  • Fee structure: Compare trading fees, withdrawal fees, and deposit fees. Check for any hidden costs or tiered discounts.
  • Asset coverage: Confirm that your desired cryptocurrencies are listed and available in your region.
  • Liquidity and volume: Check 24-hour trading volume and order book depth for your target trading pairs.
  • Regulatory compliance: Verify the exchange's licensing, jurisdiction, and KYC/AML requirements.
  • Customer support: Test support responsiveness through live chat or ticket systems. Check reviews for common complaints.
  • User interface: Assess the platform's ease of use, mobile app availability, and available order types.
  • Deposit and withdrawal methods: Confirm supported payment methods, processing times, and limits.
  • Geographic availability: Ensure the exchange operates in your country and supports your local currency.
  • Community reputation: Read user reviews, forum discussions, and social media conversations for recent feedback.

🚫 Common Mistakes When Choosing an Exchange

  • Focusing solely on low fees: Low fees are attractive but often come with trade-offs like poor security, limited support, or low liquidity.
  • Ignoring security practices: Choosing an exchange with poor security can lead to loss of funds. Always prioritize security over convenience.
  • Not verifying geographic restrictions: Many exchanges restrict access by region. Signing up only to be blocked later wastes time and effort.
  • Failing to check withdrawal limits: Some exchanges impose daily withdrawal limits that may not suit your needs.
  • Overlooking customer support quality: When issues arise, slow or unresponsive support can be a major frustration.
  • Leaving funds on exchanges: Storing large amounts on an exchange exposes you to hacking risk. Use hardware wallets for long-term holdings.
  • Not comparing multiple exchanges: Relying on a single exchange without comparing others can lead to higher costs or missing out on better features.
