What is one thing crypto exchanges still get completely wrong in 2026?

Crypto exchanges have changed a lot over the past few years, but there are still plenty of things users complain about.

If you could fix one thing about the current exchange experience, what would it be?

Fees?
Withdrawals?
KYC?
Customer support?
Liquidity?
Transparency?
Token availability?
Something else?

Curious to hear what people consider the biggest pain point right now and what a genuinely good solution would look like.
