Very good article. Same thoughts here. Buy low, sell high, it seems so simple but most investors still don't seem to get it :-) Personally I always use: https://www.coincheckup.com I'm really enthusiastic about this site, they let you analyze every single coin out there. Check for example: https://www.coincheckup.com/coins/Xaurum#analysis To see the: Xaurum Report.
