I don't think that this kind of trading is good. It can be as passive and secondary income. I prefer to use usual long-term trading. Buy on the lower price then wait before big growing. Also good to make profits are ICOs. I think, that one of the best at the moment is ElonCity. It's an energy project. It was created to make electricity cheaper and accesible. Its main partner is Krypical Group. They had four partnerships and theu are all succesful. I think, that i this will be too.
