I see your capital OP is very small but what is your goal actually? Making it $10 in a week or in a month?
It is quite interesting to see its progress but honestly OP, having this amount and only trading shitcoins, you just waste your time unless you find it worthless anyway. If I were you, better have the challenge start with $100 and your chances of growing it is huge but if you force yourselves to trade with $3, after a few days now you probably quit.
Small capital is better way to reduce losses because if a person does not have any idea and suddenly the coins loss its value then loss will be less and you will be able to recover it soon as you learn about it.
Investing in shitcoins cannot give benefit to trader but they will loss their money immediately therefore if you are using less capital then it does not matter but if you are selecting wrong coin all the time then its matter alot because this smaller Loss will become larger after addition.
If in these 10 years of experience an OP actively trade then he will now be an expert trader and as he choosed ADA so I think its a better coin and can increase the capital of OP.
