How exactly is it a scam? How exactly have they "already made their profits and moved on"? They are still frequently providing us with updates (e.g. https://blog.bancor.network/price-floor-smart-contract-deployed-621871bd09ca). Why would they even bother if they "have already made their profits and moved on"? Why would they allow people to sell BNT at a minimum price of 0.01 ETH until 120 000 ETH are gone? Wouldn't it be better to just take all the ETH and run?
Because the people involved and the ones that are behind this ICO deal with binary options, CFD and forex trading and that's exactly what they do. This ICO is just another way to lure innocent investors who think they can become early adopters of something that will be big and profitable in the future and in the meanwhile clean up on the invested monies. BNT had already reached $2.7 - that's a 90% drop in the past 7 days - the 4th biggest drop in all currencies according to coinmarketcap.com. You'd have to be practically delusional to assume it'll bounce back and live up to the fantasies it presented.
In addition, how is it the Bancor team's fault that there was a drop in the price of ETH and that HitBTC sold BNT IOUs at inflated prices?
