Do not believe the bonus offer from Crypto Trading Option (crypto-tradingoption.com). The turnover requirement is designed so you can never withdraw. I learned the hard way. I deposited through a forum discussion and the bonus terms were buried in pages of small print. My fault for not reading but their design is predatory.
Pros: Clear documentation|Intuitive for beginners|Transparent fees|Competitive fees
Cons: No crypto staking|Slow to add new assets
