Do the rich now begin to invest some of their money in bitcoin?
It is not quite clear what you mean between the "conglomerates" and the "rich"
If you refer to investment companies (such as hedge funds and their likes), this is unlikely since Bitcoin is mostly not regulated so far, at least, not to a degree where such companies are allowed to legally invest in Bitcoin. On the other hand, if you mean wealthy individuals, some of them (like the Winklevii twins) already bought some coins in the past and even created a few businesses involved with Bitcoin (say, Gemini the exchanger). But personally, I don't think there are many institutionally wealthy people who are very interested in Bitcoin (of Warren Buffett caliber)
Because it's probably not clear even to OP, who missed this topic in its
hundreds of iterations. Anyway, I have no doubt rich folks are getting into bitcoin.
Where do you think all this cash came from to support the rise to $4300? It's a
bunch or wealthy individuals. And you know people like the winklevii twins got
skin in the game.
