Yes, BNT is raising since half of December, and already above $6 on Binance. I think it's highly probably to hit 0.01 ETH ICO value again, which means about $8.8 with current ether price.
Is there somewhere a graph where to follow the evolution of Bancor's price vs Eth? This is actually the most interesting tendence to analyze.
I dont know if there is a chart to analyze of the BNT / ETH pair, but you can check the charts of BNT / ETH on the exchanges where BNT is traded against ETH (Bittrex).
I agree with you that this is the most important thing to look at when evaluating BNT's price. If you didnt know, the exchange rate of BNT at the TGE was 100 BNT / 1 ETH.
I know very well, I have been one of the buyers in the few frantic hours of the ICO - and then again as soon as they have started to trade -
actually I think at the time I had bought the most expensive BNT versus ETH ever
