It is true that no one can control bitcoin, even large countries cannot possibly control bitcoin.
While bitcoin is the only cryptocurrency that does not have a holder behind it, so no one controls bitcoin itself, even the price of bitcoin cannot be regulated.
Unless someone is able to massively adopt bitcoins with at least more than 60% of the bitcoin supply he holds, however I think it is very unlikely anyone can adopt more than 60% of bitcoins.
No one can control bitcoin is true, but I doubt when you say bitcoin price is not regulated. Although bitcoin is decentralized but bitcoin price is being listed on centralized exchanges, so price correction is possible, as long as the government really wants to crack it down, then bitcoin price regulation will not be too difficult for them.
That's what I'm afraid, once the regulation is in place, the government will intervene in the market, in addition to controlling us, they can also adjust the bitcoin price to their will.
