Someone has said bitcoin is of no value, in my heart I think they said is wrong, I always think that bitcoin is valuable, but I didn't understand what is the origin of the value of bitcoin, why accept more people, its value will rise? If you have other ideas, please discuss.
Bitcoin has been become a medium to exchange, in this means already become a money/currency, because there are a demands and also have a supply, both is determine how much value the things.
Why accept more people? Because bitcoin is actually easy to use, there's no border for you to use it, people can have their own bank, but the regulations is the obstacles.
Value will rise? Depends on the demands. Supply < demands = price rise, vise versa.
