When I was starting, I just bought a few altcoins and try and hold on it for a few months. Around 2-3 months as far as I can remember. Then suddenly this coin has pump hard like 100% that I quickly started to dump my coins as well and really profit big. I was so happy back then that I decided to try my luck again. So I'd a couple of months for starters. One good example I would like to tell how quickly it is for some is that when bitcoin fell around ~$1800-$1900 like couple weeks back and if you have bought them, and the price went off the roof in like 24 hours around ~$2900, then its $1000 easy profits if you get 1BTC then. So that returns for 1 day is already big. And then you can roll your funds again to buy back bitcoin. So its just a matter of good timing to really profit good in crypto trading.
