When I was looking for some place where I would try little bit of gambling via derivatives market (esp. perpetual) and high leverage I have found out Bybit which is quite well known (now there is advertisement around each corner of internet). The Bybit recently alongside derivatives market open also spot market and added a lot of new features such as earning (staking / saving) on lot of assets (some are quite unique). I was really galvanized by their massive promotion and free bonuses which you can use to gamble completely for free. If you are lucky or skilled enough you can earn decent amount of money. Bybit is especially great opportunity for heavy leveraged trades because of their regular trading competitions. Overall if you are more derivatives trader than spot trader Bybit is one of the first choices for you. The fees and liquidity are good enough.
