The only set people that see Bitcoin as a scam is those that has no or little knowledge about Bitcoin, for me , I think Bitcoin has outgrown the level of people still thinking that it is a scam, the record is straight, the value is everywhere for everyone to see unless people that are limited by the access of smartphones or Internet service, Bitcoin stands on a smooth priocess, this has earned a good reputations, Bitcoin has accommodated many wealthy folks in its investment terain, so I don't see why an informed person will see Bitcoin as a scam, although scam is in its rise but not in Bitcoin setting, as an investor once you know how to buy and the wallet to use in holding your Bitcoin then you are good to go, in every investment, rumour carriers do exist but the ability for you as inveetor to figure out what you want is what make you special among all, as for me no matter what they say, I am informed and no one can change my mindset towards Bitcoin investment.
