Bitmex and alternative leveraged platforms let you trade with small amounts that profit/loss ratio is equal to more big trading positions. I suggest checking CFD contracts of cryptocurrencies on forex brokers that offer leveraged crypto trading. Decide on your own risk.
Thank you but I see cfd contracts for absolute minimum of 10 dollar. Im looking to scalp 3 or 4 dollar
Almost all brokers have minimum deposit requirements and it is not understandable why you want to scalp 3 bucks less than 1$ balance. You can deposit 10$ and after successful trading positions you can withdraw your balance but don't touch the amount which you can't afford to lose on scalping.
