I agree, don't hold coins that have no product or real life value to them. There are a lot of coins and tokens that the investment you put into them is used to do some good things. Those are the gems you need to find and buy if you want long term value. Ethereum, Neo, Steemit, LBRY, DTube, Decentraland, Bezop, Envion, Solarcoins, KWH coins, Buzz Coin and many many more that all offer real value service instead of just stores of value.
