I will do the same when I become influencer on social media with many followers and fans, they will shill and hype for the mass to get 9n board of financial freedom.
If bitcoin reach 100k, the entire market capitalization of BTC should be around 1.8 Trillion. Where do you expect that money inflow from? Perhaps in the future when BTC is fully recognized, adopted as store of value and not restricted in some countries.
The same people that are predicting 100k will be the first to sell when Donald Trump make a negative tweet about BTC. For now, i don't see BTC above 20k.
I think the money inflow could be mainly from all around the world when the fiat currency gets worse and worse, there are more and more people coming in, that means the money come from people who are sick from fiat losing a lot of value, same people who buy gold for assurance.
Also there will be a lot of big corporations who will add more people (or create if they are late already) crypto spaces of their companies and keep investing there, wall street will continue to put a lot of money into bitcoin for sure, more people ask about it to them the closer they will get to making a huge crypto part in their companies. Combine those two and we are going to have close to 2 trillion dollars worth of bitcoin, it just makes too much sense and sounds logical, I don't know if I could be wrong with either of them.
