Soros, as an old-school financial player, needs to take a certain amount of time to accept Bitcoin.
~snip~
The conclusion is that I think Soros has discovered the potential of the cryptocurrency market and is ready to study how to buy it.
I would say that he's most certainly not alone in that, he has plenty of younger employees who were already telling him about Bitcoin, possibly for years.
I would add that most probably he has studied this - now and then - and now, since other prominent companies have joined the show, he decided to come too. Most probably he has waited for the first major dip after corporate money has became known to flow in.
He may be already buying the dip or he may have bought already. Companies like this don't tell the media exactly what they do and when they do it.
