Big Banks want to destroy Bitcoin before it destroys them.Bitcoin, the “people’s currency,” has the potential to become a new currency, free of the control of big governments and big banks.
That’s why they both want to limit this potential. Each one in their own way. Big governments by stepping up regulations of Initial Coin Offerings (ICOs) and by shutting down cryptocurrency exchanges, as the Chinese government has announced recently, crushing cryptocurrencies.

They just need a pause to figure out, how to treat with exchanges, taxes, ico`s.
