Which crypto exchange is best for buying Bitcoin?

Question

Accepted Answer

Here's a neutral comparison of the top exchanges for buying Bitcoin, based on the directory data. All six are solid, beginner-friendly spot markets with basic KYC, so the real differentiators are fees, liquidity, and trust.

Exchange	Maker/Taker fee	Trust score (per CoinGecko)	Est.	24h BTC volume
Binance	0.10% / 0.10%	10	2017	122,351
OKX	n/a	10	2017	25,069
Bitget	0.10% / 0.10%	10	2018	11,941
Bybit	0.10% / 0.10%	9	2018	22,973
MEXC	0% / 0.05%	9	2018	15,928
KuCoin	0.10% / 0.10%	9	2017	18,534

What stands out by dimension:

Cheapest fees — MEXC has the lowest taker fee of the group at 0.05% (0% maker), about half of everyone else's 0.10%. Best if fees are your main concern.
Deepest liquidity — Binance leads by a wide margin on 24h Bitcoin volume (roughly 5x the next largest), which usually means tighter spreads on big orders. It also has the top trust score (10, ranked #2 per CoinGecko) and serves users globally.
Highest trust alongside solid volume — OKX and Bitget both carry a 10 trust score, though their volume is a fraction of Binance's.
Bybit and KuCoin sit in the middle on both fees and trust.

One practical note: Binance is the only one of the six that doesn't carry a "does not serve US-based users" flag in the directory. Bybit, OKX, MEXC, KuCoin, and Bitget all note that they don't serve US users — so if you're in the US, Binance would be the main option on this list.

Since you asked broadly without a region or fee concern, this is the trade-off in plain terms: MEXC for the lowest fees, Binance for the deepest liquidity and widest global availability. If you tell me where you're located or how much you care about fees vs. ease of use, I can narrow it down further. This is informational, not a recommendation to buy.
