I just hodl coins until I reached my goal, I strongly believe crypto currency have great future and It just started only their journey, more to come.Crpto currency will grow in huge next couple of years, if you hold the coins for 3 years sure you will get good profit, when more people knows about crypto the market cap will reach trillions, now days only bitcoin knows more people. In future lot of coin will generate and crypto will go ahead a lot.  I like trading but I also think crypto will play a very important role in our lives in the future, so I exchange my profits from trading to fiat, because I do trade like a part-time job, but I also keep some coins for the long term as an investment plan.
