Very good article. I was about to post a similair thread. 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 Every single coin can be analysed here based on: the team, the product, advisors, community, the business and the business model and much more.
