O bitcoin and cryptos in general are either the future of economies worldwide, or are going to get squashed by the government.

In the instance of a ban, Im assuming all the government will end up doing is drive the prices to ridiculous amounts, crpytos will be used extensively in the underworld(as it already is in the dark and deep web). Due to its decentralized nature, governments wont be able to trace, or ban cryptos completely and it may actually have the opposite effect, more people may utilize it.

On another hand, governments could turn it into another form of currency, using their massive infrastructures and power to mine, control, acquire and distribute it, turning cryptos into something similar to fiat money. in this case, I believe countries will adopt a two money system, one for normal transactions, and a fluid, dynamic one( crypto) for digital transactions.
