If all countries legalized Bitcoin, the Bitcoin price would be more stable than it is today. Of course we will find it difficult to see a bull market as we feel today. And while currently Bitcoin is not legal in many countries, I see no restrictions for the use of Bitcoin so far. We use Bitcoin so far it's still smooth, I haven't found a blocked Bitcoin wallet. Of course if Bitcoin is legal, and certain rules are in place, I'm sure there will be high taxes here.
