Nice blog. 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. I found this great website: 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. Check for example: https://www.coincheckup.com/coins/DigiByte#analysis For a complete DigiByte Detailed analysis.
