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 with you bitcoin is not useless as long as it helps people. Whoever you are, we will not force you to like bitcoin because it will not change the fact that many of us here are benefiting from this cryptocurrency.
