I think its price worth same value as paid Roger Ver - 1m$. If somebody bought it for that money then it costs that money.
As for price of selling: it depends on bitcoin future. If people will forgot about bitcoin as about financial bubble then price would be 10,000$ or so. If bitcoin will become popular again and its price will raise and raise then the price would be even 2m$ for sell.
He only paid 1 million for it? Quite surprised but I guess he bought it before the 2017 bull run huh. I'm not sure anyone would spend that much on it now who had money or the Roger Ver attitude.
I'm pretty sure he paid even more for the Bitcoin Twitter handle. OR was it someone else now that bought it?
Who cares though right? I do pity all the newbies who bought BCH by accident because they went to Bitcoin.com!
