Nice blog. 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 The site lets you check all there is to know about the team, product, communication transparency, advisors and investment statistics on every crypto. For example: https://www.coincheckup.com/coins/Nxt#analysis To see the: Nxt Detailed report.
