Only a few rich people have this mindset with regards to Bitcoin so I don't think they are all in on it, however can you imagine how it will be when the time comes that a lot of billionaires will change their views towards Bitcoin? I can possibly see a price surge happening because of it since now we have news kinds of whales suddenly panicking to buy more and more Bitcoin in their portfolio. The downside ofcourse is them having a big control or influence in the market where they can short or go FOMO anytime.
Bitcoin is perhaps the most liquid asset available right now and therefore you can expect extreme volatility in the near future, which results from panic selling and shorting. Now this is something that we need to accept, along with the influx of funds from the institutional investors. Some of them may be in for the long term, but I suspect the majority would like to make a quick buck and then exit.
Nope, Bitcoin isn't the most liquid asset out there and that is for all kinds of assets not labelled as fiat currencies, this includes stocks and mutual funds since they aren't in a liquid form. When we say liquid asset we are talking about assets that are acceptable for what it is as a mode of payment and as of right now fiat currencies are still the most accepted mode of payment out there. But you are right to say that they are not here in the long haul since companies like this one always likes to adop and open up their options just to maximize their profit.
