I think for now it's very hard to be regulated. Yes it is accepted and recognized by many countries regardless of the decentralized. Maybe soon through a certain process it will be regulated but not now.
Right now, the value of bitcoin is low, it will be harder to all of the people to accept it at low price. But there are some people who already accept it completely.
But for people who have big money accept bitcoin price now because they can buy a lot of bitcoin at the market. I am sure that soon, all people will accept bitcoin because they know that with the low price of bitcoin, they can make a lot of money in the future. I think maybe the government will make some regulation related to bitcoin but I still curious about what the regulations that they will make.
