This is a welcome discussion point. Nice to see I'm not the only one who thinks like this. Sell the coins that you know nothing about. Do proper research on any coin you buy. If the market falls at least you can hold your coins knowing they have a long term future. This is quite an interesting website I found: https://www.coincheckup.com It's a great site that gives in depth research on every tradable cryto in the market.
