If that will ever happen, It won't be the work of famous figures in the industry but rather because of the institutional investors slowly getting their investments right with Bitcoin. After the Tesla news, I believe that it attracted a lot of institutions to do the same and I believe that's going to be a big jump for Bitcoin. Bank of NY Mellon last week even said it formed a new unit to help clients own and trade digital assets.
I have been watching
BTC on KuCoin and I've seen it hit the ATH just recently, Bitcoin was consolidating under the $38,000 resistance area for a prolonged period. This presented a risk to the short-term bull cycle of Bitcoin. Resistance is quite strong on $49900 though so I advise everyone to be really careful trading.
That is a possibility however I am more inclined to believe that what we are going to see in the near future is that more institutional investors are going to reveal that they had already invested in bitcoin, I say this because the price is already very high and while it is obvious that institutional investors have the money to invest in bitcoin at whatever price they want I am not so sure they will be too eager to come to this market when the price is already too high, most likely they have been buying all the bitcoin they could when the price was under 10k and right now they are just holding.
