In the beginning of crypto people believed in it. But as the numbers went up and up and up it attracted the wrong people. And the original people left.
Now the traditional banking system is basically rebuilt in crypto. The banks are busy the exchanges. The EU even talk about making it illegal to store money in your own wallet.
It's money, did you think it wouldn't attract the wrong people?!
This is what happens when people don't think things thru.
The traditional banking system does not use cryptocurrencies.
