Investing in cryptocurrencies is very cool. I can recommend you to look at the site https://www.meteoprog.com/crypto/kraken/, where I successfully learned about kraken and was able to buy cryptocurrency. This is a good exchanger, where I can earn on the difference in exchange rates. You can also try if you understand this topic a little. If you do not understand, then it is better not to go there. Therefore, before this, it is better to learn to read a lot of information.
