Good points in this article.  Interesting to see I'm not the only one that is thinking about 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.  An interesting website I found:  https://www.coincheckup.com This site is really helpful in my coin research. I don't know any other sites with so much indepth analysis.
