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.
The point is, why he still here if bitcoin is useless. Bitcoin has it's disadvantages that users may affected because of it's too long for transactions. I believe it will soon resolved for that matter, bitcoin has helping a lot of users mostly others become rich.
