We need to stop calling these a "scam" and rather just point out the bad business plan. There are true scams and no one is listening when we point out bad business and pump and dump fake coin forks as the same thing.
BANCOR IS NOT A SCAM.
However, they would have to be VERY successful for you to make your money back given the ICO size.
They have a neat tech and the fundamentals of increasing liquidity through their token process is all good. The bad side? I just don't see how they will ever be popular enough to make back the money raised for the investors. The pump of ETH has really set everything down stream into a hype frenzy.
We wouldn't care about 400k ETH being raised if ETH was at a mature value. But currently, there is a good market high and a 30%+ correction will come, wiping that fiat value out of BANCOR with it.
