With a crypto market that consists of more than 1,300 coins, it is easy to experience choice overload when it comes to investing in it. Although Crypto20 (https://crypto20.com/en/) is a convenient way to diversify your portfolio and be exposed to the ups and downs of several coins (I invested in it myself), you might want to create your own diversified portfolio. In that case, it is good to investigate the fundamentals and price movement of coins thoroughly.
I am not sure how seriously the creator (see picture below) of the following summary of the top 100 cryptocurrencies has investigated them, but quite some descriptions do resonate with me. Please let me know how you feel about them!
