I do! I have an account on Wex trading platform and HitBTC trading platform. On wex I have just .0023 BTC and use it to buy low sell high and steadily build up my BTC. On HitBTC I put everything into Ripple coin (XRP) because I think it's a good long-term investment. I already doubled my money on Ripple in three days because I bought at a good time, but I'll be holding it for a year at least.
