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.
You are so true. If BTC is a scam why is it that there are lots of us here? And why is that the people I known became rich because of this? There are lots of investors here that are living now in their decent homes and riding in their luxurious car. These are evidences that BTC is helping people and it is true!
