I personally am a daily trader, and that is for my life. You are right, most daily crypto traders are a loss. especially newcomers. and those who are profitable are big players. but I personally can still make a profit, but have to make extra analysis. like searching for news and looking at chart patterns. because if only with feeling. it will make me lose. and very emotional.
Don't get emotional, it's the number one adversary of the day traders.
Yeah daily trading is getting harder, I've been taking a break for 2 months, but that applies to altcoins trading. at the moment I'm more focused on bitcoin, bitcoin has great potential for daily trading with his fluctuations.
There are other altcoins that's way better to trade than bitcoin. I'm a bitcoin holder and I choose not to touch it and just let the other altcoins apply day trading. Doge and Litecoin are good candidates but if you're better in that strategy, continue.
