Zero-Fee Crypto Trading: Which Exchanges Actually Offer It?
Spoiler: True zero-fee trading doesn't exist. Here's what "commission-free" really means.
No exchange operates for free. "Zero commission" platforms make money through spread markups (0.30-2%), payment for order flow, and other hidden fees. The lowest actual cost is ~0.16% on Kraken Pro.
The "Zero Fee" Myth Explained
When an exchange advertises "zero commission" or "fee-free trading," they're being technically accurate but practically misleading. They don't charge an explicit trading fee—but they make money in other ways that often cost you more.
How "Free" Exchanges Actually Make Money
The Spread
They show you a higher buy price and lower sell price than the actual market. That gap (typically 0.30-0.50%) is their profit.
Payment for Order Flow (PFOF)
They sell your trade information to market makers who profit from knowing what retail traders are doing.
Interest on Cash Balances
They earn interest on uninvested cash sitting in your account—money that could be earning interest for you.
The Golden Rule
If you're not paying for the product, you are the product. "Free" exchanges monetize your trades in ways that often cost more than paying an explicit fee would.
Case Study: How Robinhood "Free" Trading Actually Works
Robinhood pioneered "commission-free" trading. Let's break down exactly how they make money on your crypto trades:
The Robinhood Spread
Say Bitcoin is trading at $100,000 on major exchanges:
Robinhood Buy
$100,175
Actual Market
$100,000
Robinhood Sell
$99,825
That $350 spread (0.35%) is Robinhood's hidden fee.
What Robinhood Says
"Commission-free crypto trading"
What You Actually Pay
~0.30-0.40% per trade via spread markup
On a $1,000 Bitcoin purchase, Robinhood's "free" trading costs you approximately $3.50. That's comparable to Coinbase Advanced's explicit 0.40% fee—but less transparent.
"Free" vs. Low-Fee: True Cost Comparison
Let's compare what you actually pay across different platforms on a $1,000 trade:
| Exchange | Advertised | True Cost | $1K Trade |
|---|---|---|---|
| Robinhood | "$0" | ~0.35% (spread) | ~$3.50 |
| Webull | "$0" | ~0.50% (spread) | ~$5.00 |
| PayPal | "No fees" | ~1.5-2.3% (spread) | ~$15-23 |
| Coinbase Advanced | 0.40% | 0.40% | $4.00 |
| Kraken Pro (maker) | 0.16% | 0.16% | $1.60 |
| Gemini ActiveTrader | 0.20% | 0.20% | $2.00 |
The Irony
Exchanges that clearly state their fees (Kraken, Gemini) are often cheaper than "zero commission" platforms. Transparency beats marketing.
What About MEXC's 0% Maker Fees?
MEXC advertises genuine 0% maker fees on spot trading. This is real—but there are caveats:
✓ The Reality
- • 0% maker fees are real
- • 0-0.05% taker fees
- • Lowest spot trading costs available
⚠️ The Catch
- • Not officially available to US users
- • Operates in regulatory gray zone
- • Risk of account freezing
- • Limited recourse if issues arise
US Users: Don't Risk It
Using offshore exchanges like MEXC violates their terms of service. Users who are caught face account freezing with funds potentially locked. The 0.16% savings isn't worth the risk.
What About Binance.US 0% Bitcoin Trading?
Binance.US occasionally offers 0% fees on select BTC trading pairs. This is a legitimate promotional offer:
The Fine Print
- ✓ 0% trading fees on BTC/USD and BTC/USDT pairs
- ⚠️ Only applies to Bitcoin—other coins still have fees
- ⚠️ Promotional—could end at any time
- ✗ Not available in New York, Texas, Vermont, Hawaii
For Bitcoin-only traders in states where Binance.US operates, this is genuinely the cheapest option—when the promotion is active.
The Lowest Actual Fees for US Users
Forget "zero fee" marketing. Here are the exchanges with the genuinely lowest costs for US customers:
Kraken Pro (Maker Orders)
Use limit orders on the Pro interface. Available in 49 states (not NY).
Gemini ActiveTrader (Maker)
Available in all 50 states. Great for NY residents who can't use Kraken.
Bitstamp (Maker)
Available in all 50 states. 0% fees for accounts under $1K/month volume.
Why Transparent Fees Beat "Free"
❌ "Free" Trading
- • Hidden costs in spreads
- • No control over execution price
- • Can't use limit orders
- • Worse execution quality
- • You are the product (data sold)
✓ Transparent Low Fees
- • You know exactly what you pay
- • Limit orders = control your price
- • Maker fees = even cheaper
- • Better execution on order books
- • Straightforward business model
Frequently Asked Questions
Is any exchange actually 100% free? ▼
No. Every exchange needs to make money somehow. "Zero commission" always means hidden costs elsewhere—usually spreads. The closest to free is Kraken Pro's 0.16% maker fee.
Why is Robinhood free if there's a spread? ▼
Robinhood's spread IS their fee—it's just not called that. When they mark up the price you pay, that markup is their revenue. It's commission-free in name only.
Is Robinhood still worth using for crypto? ▼
For casual buyers who want simplicity, Robinhood is fine—the 0.35% spread isn't outrageous. But if you trade frequently or care about getting the best price, Kraken or Gemini are better choices.
How do I know if I'm paying a spread? ▼
If the exchange doesn't have a visible order book or doesn't let you set limit orders, you're probably paying a spread. Compare their quoted price to real-time prices on CoinGecko or CoinMarketCap.
The Bottom Line
"Zero fee" crypto trading is a marketing gimmick. Platforms that advertise "free" trading make money through spread markups that often cost you more than exchanges with transparent fees.
The best approach: Use exchanges with clear, low fees (Kraken Pro at 0.16%, Gemini ActiveTrader at 0.20%). You'll pay less than "free" platforms while knowing exactly what you're paying.
