Come on who doesn't want the ability to trade cryptocurrencies with way more then you actually have or in this case contracts this is very profitable but most definitely has risks but in my opinion if you make well informed decisions and have ample collateral and know when things are going bad to cut your losses and reposition yourself you will do fine and may very well put your self in a position where leverage is almost not needed and then risk will be significantly reduced. Trade smart and enjoy your rewards
