We never know if some bigger names start to participate then buy some Bitcoin and that's for sure will start a new push of the price to hit a new ATH. But if there's no new big institution/bigger investors then we should slowly expect a slowly decline of price over time. But I don't know what price is the support would be.
On the contrary, I think that those who come with bitcoin investments today are very serious. For a long time, we have seen distrust in the dollar. Investments by large companies in bitcoin are now considered a lifeline to keep their businesses running. Managers of large companies build long positions with a price tag of $100.
Charlie Lee's recent announcement that other companies will follow Tesla seems like a good prediction today. Moreover, just yesterday we saw again that MicroStrategy again bought bitcoin for $300 million. And while the price of $45,000 will be held, I think it is not worth waiting for some strong volatility.
