Bitcoin is not a scam but unfortunately, scammers make use of the name Bitcoin as a tool for scamming.
So many people misunderstood it and we can't blame them either because of lack of proper education and some influence also from those who become a victim of scam through the name Bitcoin.

And I could say that no matter how reliable is Bitcoin to us but it has no escape from negativities spread around. And it was hard to convince people who already have negative in mind. That is why I don't encourage someone to invest here if doubts are in their mind, this is not meant for them.
