Unpopular take but this is inevitable as bitcoin grows. Say the ultimate theory of hyperbitcoinization comes to pass in 20 years or something. Do you think everyone owning bitcoin is anarchist intellectual fighting the good fight? No... Bitcoin is going to be like water to the fish that swim in it, and 99% of the people won't care about it beyond that.
People buying bitcoin due to Elon's tweets will come and go and cause volatility, but it's an inevitable step in the larger journey of this technology. Gatekeeping will only cause your own blood pressure to go up, so I'd just make sure I got my keys in a safe place, buy the dips that result from these sudden adoptions and go with the flow.
Also, every newbie who comes along because of Elon has a chance to evolve into a lifelong holder. In the short term, it can be annoying but in the long term, it'll strengthen bitcoin.
What are your thoughts?
I think that as the market grows and more people use Bitcoin, it will eventually become less volatile. Elon Musk's opinion is important to some people, but if there were significantly more users, there would be a lower chance of his audience making a big impact because the community would be more diverse and people would admire different celebrities. So when one such guy says something bad about Bitcoin, his admirers will still sell their coins, but it will be insignificant for the market overall.
On a side note, buying and selling based solely on his tweets is a bad idea even nowadays when he has some power because many other factors contribute to price changes.
