Bitcoin price increase depends on supply and demand and not on anyone, you should remember that bitcoin is decentralized and no one can control it alone. We don't know how much bitcoin he is holding but he is like us as an investor, we are all the same so his selling or holding is not a big deal to affect the market. In the past he has tried to find ways to manipulate the market for his own gain so be careful what he says, he is just a new entrant in the market. If you look back at the previous times bitcoin hit ATH, you will see that bitcoin doesn't need anyone's help or depend on celebrities to hit ATH. It has enough power to do it on its own, it's only a matter of time.
