Nope. If he had the cash there, he likely would have eaten the whole wall in a couple bites. As it was it took 6 or so hours, and he got less than half of it.
Money talks. He got somebody out of bed, or flew in with a suitcase full of cash, who knows, he didn't share details - but he has in the past.
you seriously believe that? flew the cash in? got someone out of bed and got all that cash there in <6h? to Slovenia? and how well do you know this guy? there are a lot of big talkers on the interwebz.
all he said is this: "Fiat arrives (finally.)" did he actually say he bought the wall?
no, no. it's WAY more likely Pantera Capital, being an equity owner and close associate of the founders, would be the ones there waiting with the required large amount of fiat to take down the wall.
