Frequently asked questions about crypto exchanges
Do you need to pay tax when exchanging cryptocurrency on an exchange?
In most jurisdictions, yes. In Russia, the exchange of crypto for crypto and crypto for fiat is a taxable event. EDC (exchange rate difference) is taken into account as income. Check with an accountant or tax consultant.
What are maker and taker commissions?
Maker - you create liquidity (limit order). Taker - you take liquidity (market order). Maker commission is usually lower (0-0.08%), taker - higher (0.05-0.1%).
Is it possible to trade crypto without KYC in 2026?
On DEX (Uniswap, dYdX) - yes, without verification. On CEX - only up to certain limits (on Binance without KYC the limit is 0.06 BTC per day for legacy accounts). Full trading on CEX requires KYC.
How to safely withdraw BTC from an exchange or exchanger?
After an exchange or withdrawal from a pool, it is important to execute the transaction correctly so as not to lose funds due to commissions or errors:
| Stage | What to check | Risk in case of error |
|---|---|---|
| Address recipient | First 4 and last 4 characters | Loss of the entire amount |
| Network | Bitcoin (BTC) vs Lightning vs others | Loss if the network is wrong |
| Commission | sat/vByte on mempool.space | Transaction freeze |
| Minimum withdrawal | Check with the exchange before beginning | Blocking of small amounts |
In 2026, the fee on the Bitcoin network during normal loading is 10-30 sat/vByte (1-3 $/transaction), at peak - up to 200+ sat/vByte ($20+). Before making a large withdrawal, check mempool.space: if mempool is full, it is better to wait 1-2 hours for the fee to decrease. Never enter an address manually - only copy+paste and visually check the first and last characters. Clipper viruses replace addresses on the clipboard. For larger amounts, use a hardware wallet with address confirmation on the device screen. Compare BTC withdrawals from different pools and exchanges on POOL BTC.
Bottom line: CEX or DEX - what should a miner choose to exchange BTC
For a miner who regularly withdraws BTC and converts some into fiat, CEX (Binance, Bybit) is the right choice: liquidity, minimal spreads, simple withdrawal to the card. DEX is needed for specific tasks: exchanging tokens without KYC, participating in DeFi, exchanging non-standard pairs. When exchanging more than $10,000 per month, it is worth comparing spreads on several exchanges: the difference is 0.1-0.2% = $10-20 for every $10,000. Keep an eye on the minimum withdrawal amounts of BTC from pools and exchange fees through POOL BTC.
