Fine thread. Good to see I'm not the only one that is thinking about this. The price of a coin should depend on the quality of the product, the team behind it, if proffesional investors believe in it, and a lot more facets. Personally I always use: 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. For example: https://www.coincheckup.com/coins/Eos#analysis For the Eos Investment analysis.
