Interesting blog. Thanks for bringing this to my attention. The quality coins are here to stay and it's like buying in at the S&P 500 50 years ago. Cryptos will fall and rise at a more rapit phase any investment market has ever seen. Just hold (literaly) and enjoy the ride. We do need to look better at the insights of every coin. What team is behind it, is there any management. How strong is the product, is there any product at all? Besides coinmarketcap.com there is: https://www.coincheckup.com This site did all the research for you. It's truly amazing.
