Biden regulation will of course greatly affect the global market, but I would never believe that bitcoin will be destroyed just because of what he did, indeed the price of bitcoin continues to decline in the market and actually it is a natural thing if the market continues to be hit by negative sentiments like what happened right now, but to destroy bitcoin it seems that biden has no power over it.
So of course we don't need to be afraid or panic about what is being rumored, because as long as many people in the world believe and continue to make bitcoin transactions, of course bitcoin will continue to grow all the time.
Biden could definitely cause the price to go down. He doesn't have the power to make it go away, nobody has that power, not even Satoshi has that power, satoshi could come up together and say that his bitcoin idea was bad and should be stopped and it is a shitty one, and people will ignore even him after a while.
What these type of things cause is just drop the price for a while, have a bear market, and then eventually but slowly go up once again. That is why these are all "short term bad news" and nothing more, you need to end up getting better at realizing that the long term trajectory of bitcoin is always up, no matter who does whatever.
