the market is starting to recover, there is no point in selling coins now, the cost is too low, you need to wait a bit, it will be a shame if in a year your coin will cost thousands of dollars.
If a person keeps from 2017 then of course you just do not need to sell , I think it's worth keeping the course until the moment when there will be a bullish trend and it will be completed as in December 2017
I also chose to invest in projects because it is foolish to sell coins that did not flourish. Yes, most projects unfortunately cease to exist. However, all that we do today will help us in the future.
