Capital with 10 USD I think is very small to get rewards, maybe with 10 USD can be used for trading, not for Stake, Earn or Mining. But trading also if the capital of 10 USD is very long to get big profits. I can't give more advice because the capital of 10 USD is very small in my opinion.
Indeed. It is too small funds. I think it is not enough to be the capital for trading, mining, or even staking. At least, we should have $50 - $100 to be the capital of trading. If we want to be easier to get good amount of money, I think it is recommended to use $500 at least. If we only have small funds, it is recommended to invest than to trade. However, it will take a longer time to take profits if we choose investment.
