Very good blog. I fully understand what you're talking about. The trustworthiness of the crypto is based on: A solid team, product, advisors, preferably VC investors, etc. Sell all cryptos that don't have this solid background. It's a waiste of money. Besides coinmarketcap.com there is: https://www.coincheckup.com. This site gives a complete analysis and investment stats on every single tradable crypto out there.
