You cant because that is not possible. Everyone would have done the same and would have taken big lessons to do it. However, earning upto 10% is only possible if you have proper trading skills and this would be about the day trade I guess. Because there is no other way which can efficiently earn you everyday. However with day trade you can earn around 2-3% of the profits daily which is 4-6 dollars of your total amount. However, this all be followed by some risks where crypto might be getting very mean and may be dumping itself below your entry point of trade and thus loosing you more than 10% in single day. If that happens then you have to start from the beginning and thus this cycle could be hard to get more than 10% profits daily. Go for the small amounts.
Oh, it's a pity, I also wanted to earn so, I really thought there is such an opportunity. I also trade on the stock market during the day. In most cases, this is called arbitration. But I don't have very good results. About 2-3%, as you wrote. Sometimes even in minus'm leaving. I agree that this a fairy tale. But personally, I have not tried signals from various traders, they say they give a great result. I haven't.
10% daily is too much although is a near to almost near to impossible unless you're sprinkling out your coins in different alts. It is nothing to be pity of since you can't drive the market to make your wish like that come true. It is like throwing a coin in a wishing well while that wish still will evaluate on its own and not from your strategy, although your strategy could help it to reduce the losses and obviously the risk.
