The narrative has changed. It used to be Is Bitcoin a scam? now its how high do you think the price will go. Institutional money is on its way people.
Matthew Goetz from 'Block Tower Capital' stated in front of a capacity crowd at Consensus; "Bitcoin to 60k in 2018"
Pretty sure 60k$ in this year price looks scam for me because of the ups and downs of crypto coins, But I know bitcoin price will recover and will be on the 20k$ this year. Anyways why can't they build bitcoins backed from dollars? only ETH again?
