Honestly, @jrcornel , I think his sceptics are also valid. Cryptocurrencies have a high degree of anonymity which does drag in lots of criminal activities, since you are nearly unable to track the money and whom's it is under the law. As good as decentralization is, it shouldn't be used for the wrong purpose.
Meanwhile I am really excited seeing one of the most powerful people of the world not being against cryptos anymore, so the world of the blockchain and cryptocurrencies is more likely to grow!
Greetings!
