what do you call "not much"?
a 3% profit in a couple of hours isn't much? because you can do that in day trading altcoins. it is hard and i usually don't suggest it but i do it sometimes and it is possible to do. and make at least 3-5% in very short term in rising markets and get out. and there are times that a big pump happens and you can make a big 50%-100% profit in a day or two. and we have all seen them many times.
I am doing this day trading too.Almost daily I do it whenever I see an opportunity, if I can sell within a day, at least within a week with a minimal profit. But I know, you can earn more if you hold further but its OK to me, I do also have coins being hold for a longer period. There are short term and long term goal also.
