Bitcoin has already shown it can grow without needing government or corporate support. It reached a $1 trillion market cap all on its own, providing its strength comes from the trust people have in it not from any external backing. As long as people believe in bitcoin, it will keep growing.
Another attestation was that when China banned the use of bitcoin, a big economy trying to influence the decision of the market. And yet, this currency continues to proliferate and expand without the interruption of any country. We can say, bitcoin or the crypto market can truly withstand on its own, even without the politicians or the government supporting on it.
