NVOS is supposed to be worth 0.99$ and automatically tradeable for BTC of an equivalent amount - how are you gonna get all that BTC? for example when trading ETH/BTC on exchange, half of the fees is in ETH and only the second half is in BTC, when trading for example ETH/LTC, there's no BTC fee involved - how will NVO get all the BTC to trade for NVOS ?
IIRC this was answered a few times in the thread. Read through the pages or wait for nemgun to answer.
also I've never used counterwallet before - how do I use it with an address generated using vanitygen or electrum (so I can work with NVOTs), for example?
You just need to control the private key to the address(es) you've used to invest with. All you have to do is import the private key(s) into counterwallet. Pretty simple. This guide covers investing with counterwallet, albeit it does not mention importing private keys:
https://medium.com/nvo-exchange/how-to-contribute-to-the-nvo-crowdsale-d3e4453e3d7dI WAS prepared to invest in this project. However, considering the unprofessional attitude of the escrow agent that would be holding my BTC, I'm going to pass.
Bullshit. I have absolutely no reason to be friendly to anyone (not that I was unprofessional towards your statements).
