Its value is determined by demand. If people need it and believe in its future, Bitcoin is growing. Suppose, very soon, it will be accepted as money. Why not? If you are able to buy things for it, it is possible.
It will be accepted like that but I don't think it will be accepted as money.
Bitcoin in the past if a lot of people use today will be a huge one, there will be a lot of people that will be rich because of that. But, Bitcoin will stay the same, a decentralized cryptocurrency, some countries banned it, some regulated it, it will stay like that. But the thing is that its value increases the reason more people will be drawn to it making more people accept it as payment not as money.
Bitcoin is already used as money. I think it's too early to say what will be the future regulations over bitcoin in different countries. Because regulations can change, for the better or for the worse: in countries where it's banned or heavily regulated, there might happen a change benefiting bitcoin and its users.
So it won't probably stay the same, but people must force their governments to take positive actions towards bitcoin.
