I think that many can say that the value of bitcoin is a bit speculative, since you can not subject it to anything or be regulated by the price of anything, bitcoin has that price because is the price that people are willing to pay for it, of course, that does not mean that bitcoin has no value or utility, everyone gives it the value that suits them best, for example I use it for daily transactions and has made my life enormously easier since in my country I do not have any means to get electronic dollars and bitcoin facilitates that problem.
