Hello guys please I really want to ask if their is a special way or special trick of investing in crypto-currency that really make an investor generate a good return on investment. 
Invest when the hype is gone and the real valuation comes out, that's also known as market crashes. Only invest money you are more than willing to lose or at least you have the stomach to hold on to your holdings for a long period of time until the market recovers. If you are looking to make returns the soonest sell it when it rises and then just buy again on the next crash.
