But for 1.5BTC ? No I'm Not sure there will be a Buyer to offer that Price , don't Forget the Bitcoin Value now in USD , that 1.5 btc price for a Unique Domain like this is applicable back when Bitcoin was not stepping in 30,000 Level but now ? that would be 45-50,000$ mate just for a Domain ? lol that's Insane.
It is not that insane. Altcoin.ai and Altcoin.co are selling for tens of thousands of dollars. Even lower quality domain extensions like .xyz and .tech are worth thousands. This is a normal price for a brandable keyword like 'altcoin'.
