I think that bitcoin and the whole crypto was invented and created for manipulating and managing the population. To do this, advertising crypto as a decentralized currency that can not be traced.
But it can be traced and you usually can't sell it without KYC, although I'm sure there are ways. If it was created to control the population, it seems, they would have made a greater number of coins than 21 mill possible. Also, it has the potential to bypass and render the banking system obsolete. Now with DAG technology coins like Travelflex TRF have transfer times of around 30 seconds total. Banks take days. So if it was created by a branch of the government then they were attempting to oust the banking system as well. I don't really see how bitcoin controls the population.
