400,000BTC... 230 million dollars... Seems legit.
I think you're missing a zero, there. Preev's price today converts
BTC400,000 to $2.3 billion.
don't let this thing distract you, according to
top rich list there are only 4 addresses who have over 100k BTC and all of them are exchanges cold wallet.
I'm wondering whose got the money to buy that such high amount, it will be instantly became #1 as well on top rich list unless he/they separate it to various addresses.
There only a handful of people, and not too many organizations in the world that can afford such a huge purchase. But, like you said, there aren't many hodlers that can fill the request.
As for the legitimacy; both banks listed are indeed capable of handling the funds. It sounds like the buyer is willing to work with the seller's lawyer, which will allow the seller to remain anonymous, if he chooses. I don't know, maybe? Regardless, it's way out of my league.
You are right, there aren't many who can handle it but I have 2 clients who can and will. The problem is there aren't any sellers. It is family offices who are doing these deals.
