I'm not questioning his prediction, but the ecosystem will literally needed a lot of cash in the next 4 years to really push that price to even 6 digits. The only source of that is the gold investors, if they suddenly shifts their funds to the ecosystem, I'm sure that can at least get half of his prediction. Going to be one hell of a ride if we even touches $100000.
At some point there will be a massive shift of funds from every asset and industry to Bitcoin, which is just a matter of time. Bitcoin gains more credibility as years go by and that comes with more capital allocation.
The thing with this market is that even a few billion in fresh capital can make it shoot up big time. It's still an undeveloped market after all, and as long as that is the case, the increases we go through will be significant.
If central banks will start stocking up Bitcoins as well, which might already be happening, the market will dry out even further. If we look at the last years, the availability of coins has already decreased a lot and we're not done yet.
It was already difficult to accumulate even 1BTC for people in the last years, but that's only going to become more of a difficult target. At some point you may be part of the elite with 1BTC in holdings.
