Regret always usually comes later on so I wouldn't really mind it that much. You can't do anything at that point anymore anyway. You can just keep farming the coins since it seems like there isn't much difficulty anyway, so just keep farming it imo. At the end of the day it's basically money you got without spending anything (except for time), so just go for it. Pretty sure others have experienced it as well, especially in a volatile market so nothing unusual there. Even I did myself lol.

Besides, there's still a difference between profiting and not profiting at all. I'd say any profit after that profit margin is more than enough to be a win.
