According to conspiracy theory, Is it possible that the bitcoin was created by governments to gain financial strength in the modern world?
To be honest, I really doubt that the goverments are somehow involved in the creation of bitcoin. This can be seen in their behavior when Bitcoin first appeared, and in their behavior at the present time. However, I believe that at present, states are very closely watching bitcoin and are trying to get something from themselves.
I think at first we have to realize that when something similar is happening, governments are doing their best to hide and make you think the wrong way, I amn't talking directly on bitcoin but in overall, no one can give you exact answer on bitcoin's case. One can say valid arguments around the task that bitcoin is created by governments and opposite.
Personally I think that it's unlikely to be created by government because there are very smart people among us who want freedom and they create this freedom, for example let's take creator of Tor and other privacy options, bitcoin is part of that too. I wouldn't say that governments are against all of this, no, it's even beneficial for them at some point, otherwise they would ban all kind of encryption with reason that it's not safe for your life and etc. Why it's beneficial? Because they make money in this process too.
