Well, I have traded on a CFD platform when I first found out about Bitcoin and Ethereum CFDs... I started trading them with x2, x5 and x10 leverage and it was amazing. I have made around 400% profit... Then one the market turned upside down and all my profits were swept out (well, not all of them, I was lucky that I pulled out early)... This was a lesson and now I am only hodling cryptos... Good advice for everybody
