According to conspiracy theory, Is it possible that the bitcoin was created by governments to gain financial strength in the modern world?
Which conspiracy theory are you pointing out? People who know bitcoin know that it is Satoshi Nakamoto who invented bitcoin but as to his personal identity, it is still unclear until now if he is a real person or just a pseudonym which is a person behind famous digital currency called bitcoin. If it is to strengthen financial aspect of the modern world, I doubt it because until now banks and governments are still against wide adoption of bitcoin. just my opinion.
I agree with you.
No one knows what the answer is. From a different perspective, no one knows Satoshi's true identity, and it is uncertain whether this person exists or not, so it is possible that Bitcoin is a government project. But I still prefer the view that "Bitcoin is not created by the government". At present, it is still opposed by the governments of many countries, and some governments are even very opposed to Bitcoin.
