Just save more money before you start on crypto market. There is a reason why you should save more rather than starting with $10 capital which is a fee you need to pay for each transaction. If you have more funds for your capital then you don't have to worry about the fee and maximize your profit as much as possible depends on your funds. Well, if you only want to buy with your $10 and later on then that's okay or as what crwth said.
