Interesting post. Good to see I'm not the only one that is thinking about this. Buy low, sell high, it seems so simple but most investors still don't seem to get it :-) Besides coinmarketcap.com there is: https://www.coincheckup.com This site is really helpful in my coin research. I don't know any other sites with so much indepth analysis. Check for example: https://www.coincheckup.com/coins/Ripple#analysis For a complete Ripple Detailed analysis.
