I'm sure this will never happen because if the government takes over the bitcoin then our decentralised bitcoin won't be decentralised anymore. That's the thing, currently it's not regulated and it's price is increasing because we can manipulate the way we want it. We can bring up the flood of investment with big investors and can just pump it the way we want. :-)
If government is there then everything will be messed up and for sure they will manipulate the price for themselves and not for the public interest. Might do that for the millilitre use who knows. To buy weapons. Lols. So hopefully that should not happen.
I hope that government would not take over the bitcoin because probably the currency will change to decreasing point and yes obviously they were going to manipulate the price for themselves because most of the governments are corrupted.
