Good points in this post. Interesting to see I'm not the only one that is thinking about this. The decision to buy a coin should be based on real analysis of the coin. I found that people keep buying coins without have any knowledge of them. This is considered high risk. Besides coinmarketcap.com there is: https://www.coincheckup.com Every single coin can be analysed here based on: the team, the product, advisors, community, the business and the business model and much more. For example: https://www.coincheckup.com/coins/Ethereum#analysis For a complete Ethereum Investment research.
