Poloniex

A large exchange founded in 2014. The site has spot and futures trading, a copy-trading function, and a rewards centre where you can get bonuses by completing tasks. There is also a P2P section for trading BTC and USDT.

To remove the limits and get access to all features, you need to pass KYC. At the second level, you will be able to withdraw up to 500,000 USDT per day and adjust limits, and it will be faster and easier to regain access to your account.

The site has a Polo Earn section where you can do cryptocurrency steaking. The Flexi Max programme is available for ETH and USDT with different levels and conditions of earning. And in the referral programme, you can get up to 60% of the commission for each transaction of the user you invite.
