Gate.io is interested in the possibility of trading ETFs and futures, which is rare on other crypto exchanges. I also like the affiliate program with payments of up to 40% of referral commissions, but earnings directly depend on the activity of the invited users. Over three months, I successfully invited 7 people, and I earn about 0.004 BTC per month. On the downside, I would note the lack of fiat currency and the absence of a PAMM account.
