Very good post. I was about to start a similair discussion. 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. Besides coinmarketcap.com there is: https://www.coincheckup.com I'm really enthusiastic about this site, they let you analyze every single coin out there. Check: https://www.coincheckup.com/coins/PIVX#analysis To check PIVX Indepth analysis.
