Well, they got the bitcoin for zero pounds, so they're not at any loss. Even if it won't solve the problem faced by the economy, it will solve whatever they have in mind for it.
Of course, they would have made more money from it if they had kept holding it for another 5 to 10 years, but when will be the right time to sell from their perspective? Because if they wait for another 10 years, the deficit to profit ratio would have increased, and it will still not look like the right time because people will still be expecting btc to rise even more by then.
Get ready the price will change and the market will be bearish. We and those who want to own Bitcoin at a much cheaper price than now, that's the time.
Yeah, I hope they sell it in bits and not sell every the same period because putting 61 thousand btc in the market in a week will definitely affect the price, but the good thing is, bitcoin has evolved beyond this. In the past it would have been a disaster for the price, but now, I believe bitcoi will recover quickly.
