Generally, prices of cryptocurrency changes every single minute of the day without any notice. Some traders took advantage of this volatility and they engage into day trading. While it may seem tempting, the guaranty of profit is not absolute as the loss is directly proportional to the money you invest.
I remember I read an article about day traders as they lose 97% all the time and the successful day traders earn as big as someone who works as a bank teller. So, if you are willing to risk huge amounts of capital, then expect big winnings/losings at the same time.
Gaining profit in day trading is not about the capital, it is all about the knowledge and skills that you had for perfect market price analysis.
For me, it will depend on your experience + skills + knowledge = profit, if you have all of these, then consider day trading is profitable enough for you because the chances of losing are very far on your side once you know that you are good into it. Nevertheless, it does not have a guarantee that all of the time you get profit in day trading.
