If anyone still think bitcoin to be a scam, I do not think the person will be able to realize what bitcoin is actually again, many says bitcoin is a ponzi while many says it is a scam but they are all wrong. I hope they will not miss in the next bull run before they will actually understand what bitcoin is.
You are true. I also experienced being told when they knew that I was into bitcoin or cryptocurrency , they said oh why you are investing in bitcoin , it's a scam. I told them no, it's not. When I was earning thru bitcoin that time they realized it wasn't a scam. But some people also used bitcoin to scam other people, they are invited to join an investment which they said it's bitcoin and when they started to trust and invest, those scammers will hide and never contact those who invested in them, that's one of the reasons I guess why other people think bitcoin is a scam were in fact people are only using bitcoin sometimes to scam.
