I don't think that is true because in the first place once BIll Gates and Richard Branson invest $1.2 billion for sure it will be in news in TV and the value of the bitcoin will rise. And it will be trending in online. But if this two man who are rich in the in the world really invest to bitcoin it will have big effect to us and for sure possible we see hundreds thousands for the price per bitcoin why I said that because more company and millions people invest to bitcoin because they have power and influence people.
True or not, so what if these old dudes invest their billions? Yesterday, BTC volume was "only" 5k on recorded exchanges, estimated perhaps 10k including OTC and P2P... or $34 mill. This is a really low volume period, that 500 BTC used to be volume in an hour just months ago. So even at this supremely low period, that 1.2 B is still a drop in the ocean, minimal and not lasting impact.
If Bitcoin were affected, I'd be worried.
