If you look everything by this way, you can realize that almost everything is on a bubble, not only bitcoin and cryptocurrencies, a lot of financial systems like a lot of banks, governments, and a lot of bussiness are in a bubble situation, maybe we are on a bubble, yes, but this is nothing to care about at this moment. Just enjoy it and take as much profit as you can, maybe this is one of the last opportunities that you are going to have to make such that profit in less time than other investments.
