Bitcoin is not backed by any physical asset like Gold nor by any fiat currency. It makes me wonder if I should invest/trade in Bitcoin or not?
In what evidence do you really want?
you heard about it and you have as well used it for transactional purposes and people trading and investing in bitcoin all over the world and yet you needed any physical asset backend it.
Well to those who really knows the values don't wait to be, but have already made their investments, with the reduction of bitcoin the scarcity it becomes so the increase in price.
