Day trading while much more risky can lead to much greater returns. While a coin may grow over 100% in a few months let's say, it will have a cumulative volatility of much more than this amount.I am doing marginal trading when bitcoin's movements is predictable so i could have more bitcoin in my pocket.
I highly doubt, that day trading can lead to much greater returns, but I agree that is much riskier.
I don't have much experience in trading, and I am not very good at it, but I don't see it as much profitable as long-term investing, especially when take into account and the time invested.
