I just tried day trading in eth and the price fluctuations which happens continuously is something where we can make profit in daily basis, guys from today morning to evening I could have earned nearly 15 to 20$.
True, I am making between 1% to 5% by day trading ETH. When do you know how to trade and learn the market properly, it's actually pretty easy to get profit from ETH trading. But, not everyone can do that because it drains your real life sanity and mental, test your greediness and other stuff. If they fail to do one of them, they will lose their money.
