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 agree. I think it just depends on the person you're asking. I think for many people here and all those around the world supporting the cryptomarket, I would believe that they would never say that Bitcoin is useless. It introduced the cryptocurrency market to the world, being the pioneer coin. It has been the medium of many cryptocurrency traders and investors in the market, that most certainty, brought them alot of profit, and therefore, good changes in their lives. So, I think that it's very useful.
