Solid blog. I was about to post a similair thread. 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. Personally I always use: 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/Peercoin#analysis For a complete Peercoin Investment research report.
