I've just purchased 0.2 BTC worth on Bancor
On my other website dedicated towards ICO - #ICOFOMO - the Bancor was the very first post I've created.
You can buy Bancor on Bittrex.
Initial rate was 100 BNT per ETH.
When you check BTN-ETH pair it's trading roughly at the ICO levels... Maybe I should wait a little bit longer but I genuinely believe in the project and wanted to have a small stake.
