my colleagues want to start trading in cryptos and they want me to suggest a site that is the best to start trading, but i dont what to answer because there so many cryptotrading sites. So for you guys what site and app do you think is the best?
For trading with leverage there are 2 good platforms: BitMEX and BitSeven. For new traders BitSeven probably is better because of simple interface. On these sites there is opportunity to trade with leverage up to 100x, but it is too risky, even 10x is dangerous to trade now

5x is optimal
