Is it doable? Like digibyte for an example which was trading at 0.005 last month and is now trading at around 2 cents. If im not wrong that's a 5x return in less than a month. I'm looking to invest into something like that for a quick profit?
Is 500% in one day enough? If so then yes, I have done it it a few times. You need luck plus some skill like poker. 60%/70% luck.
