The real value of bitcoin is determined by the supply and demand.. If people keeps buying, then the price will be high, just like it happen with anything that you buy daily.. Like smartphones, do you think that their bussiness want their price to be $1000 each one? No, that is because people is still buying them at that price, and they can afford to make the price higher.
The same happens with cryptos, that is why it is always going up, because the demand.
i know it is depend on demand but i ask for real value of you ?
