Good post. I fully understand what you're talking about. 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. I found this great website: https://www.coincheckup.com They seem to give this complete indepth analysis of all cryptocoins. Go to: https://www.coincheckup.com/coins/Ripple#analysis For the Ripple Investment research.
