I will just start boldly. The Bancor business model is pretty close to a scam. I am sure you will not take my word for it, because this is my first post. In fact, I made this account because I find it bizarre that no one is talking about this. Let's be honest, which one of you truly tried to comprehend their mathematical proof? Not a single person who invested at least, because otherwise they would not have wasted their money. I will try to explain a little.
They collected pretty close to 400k ether. Essentially what they do, is keep .8*400k ETH = 320k ETH to themselves, and call the remaining 80k reserves. They will express this 80k in a different coin, called BNT. They assign 100 BNT to 1ETH that they received. That means there is 500BNT for every 1ETH in the reserves. Essentially, if everyone would want to convert their BNT back to ETH, they would get 1/500 ETH per BNT. Wait you say, in the white paper it says that the starting price of 100BNT will equal 1 ETH! This is true, this is where the mathematics uses a trick to hide what is going on. Their pricing formula, P=R/(S*F) ensures that the first BNT sold will be sold at a 'fair' value, namely equal to the amount of ETH you spent to buy it in the first place. After the first sell, things get worse rather quickly. Let's illustrate this by a little example:
Lets say that 10% of people who own BNT sell it back to ETH via the smart contract. For the initial price we get: P = 80k/(40m*.2) = 0.01. All looks fair. Then after the sell we get 40m*10%*0.01 = 40k, P = 80k-40k/((40m-4m)*0.20) = 0,00556. Ouch, the price almost dropped to half value from the 10% sell-off (this is different if there are many small transactions but I will get to that later).
If people buy the same amount of BNT, this is what happens: P = 120k/(44m*0.20) = 0.01364. The increase in price is not nearly as interesting for the next person. But again, this will be lower for many small transactions.
I created a plot assuming transactions are made in small batches of BNT coins. We find that the BNT value drop VERY quickly when people start selling, and does not rise nearly as fast. Essentially this just makes BNT an undesirable coin. Another weird thing about their system is that it does not consider convexity. This means that big transactions will get very different prices than many small ones. This just does not make sense, but they don't care as they simply took your money.

If you are still not convinced, consider this. They literally admit to taking 80% of your money. All they give back is some mathematical trick based on 20% of the ether that you gave them. Do you really believe they just generated x5 value out of thin air? Sorry, but math does not work that way. I would recommend getting rid of your BNT asap, or you end up all the way on the left side of the graph. I am sorry that this news comes a bit late for some of you... I didn't read their methodology until last night Sad
Maybe now you can start to add up why the ICO was strange in various ways.
As final words, don't just believe whatever I say. Think about it for yourself. I gain nothing by convincing you of whatever I write here, I am simply sharing thoughts.

We bought into BNT not ETH. If we wanted to buy into ETH, we would have simply kept our money in ETH. It is no secret that 80% of the ETH will go towards the BNT project’s development and 20% will be kept as a reserve to ensure a minimum value per BNT. This doesn’t automatically make BNT worthless or the business model a scam, because we’re buying into Bancor’s potential (good or bad).
"Essentially, if everyone would want to convert their BNT back to ETH" - Why would we all want to convert our BNT back into ETH, especially at this stage?
i dont need complicated formulas, i payed 1 eth that is around 350 euro for 100 bnt, so i need 1 bnt to have a worth of 3.50 to breakeven, everything above is my profit, this coin will go to 10$ faster than you can say money
so im all good plus its a revulotionary project that i SUPPORT plus i make profit.
some people think theyre so smart but they dont see the obvious
It's now trading around 0.031 btc or $85 per BNT

Impossible, might be a scam, because Bancor tokens are locked for 1 week after the crowdfund
