I have experiences of trading with below $10 and making more than 20% of profits. In my opinion, your capital is not a big criteria for your success in trading but your technical and money management capabilities. You may argue like to withstand against negative markets, we must need big capital but when your technical analysis is too good then you may enter at the perfect entry level from where market may not show negative directions.
Trading must be a game of skills and capital and all other things are playing just supporting roles. I agree without capital, we cannot get into trade but having very big capital in no way assure you profits; yeah, still you must need good skills.
These days I do not think that you can start trading with $10, because even the transaction fee is higher. Assuming you somehow earned $10 and it was sent to your account, then we could maybe assume that you would be doing fine by simply swapping in places like BSC, not even ETH because that would be too high fee, if you can find something cheaper and still has some volume in other chains that would be great too because BSC is getting expensive as well.
This is why I believe that we should not be doing anything with 10 bucks but to hold it, just keep that in an investment somewhere, buy cake and stake it maybe, and then try to grow that bigger, it would be a lot more profitable if we did it with more money.
