Solid article. Really appreciate you bring this to our attention. 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 They seem to give this complete indepth analysis of all cryptocoins. Sorted by team, product, company, advisors, previous investors, etc. For example: https://www.coincheckup.com/coins/DigiByte#analysis For the DigiByte Analysis
