Like anything on the planet, the value is whatever is someone is willing to pay for it, but at some point people are going wonder why the fuck they are paying so much for it, or paying for it all for that matter. Bitcoin doesn't produce anything. You can stare at it all day long and no magic rabbits are coming out of hat. So someone else might buy your bitcoin for more then what you payed for it, but now they have the problem of trying to sell it for a profit. It's not fiat money, so people can get kiddy as much as they want about different platforms talking accepting it, but will never be widely accepted like fiat money, and anyone who thinks otherwise is fooling themselves.
You are thinking in North American terms. Third world nations can't trust fiat currency. And are turning to Crypto for a more stable currency that is accepted across borders.
