I respect your point of view when it comes to bitcoin. It wasn't entirely useless if a lot of people are benefiting from it. A lot of people get rich because of bitcoin and I think it is quite rude to say it was useless.
I really agree to you. For me also bitcoin is not useless. It can help us in our financial crisis. Many users was became rich because of how they mange to use their crypto currency. Bitcoin will become useless if a user will apply it in a wrong way. It is always depends on the users on how they handle their bitcoin.
