So if understand this right and i want to invest with BTC:
1. i create a bitcoin wallet on counterwallet for example
2. i link that bitcoin adress to my personal NVO crowdsale page
3. i send my btc's to 3AiGej11G8jUXvEBPvQKPLiHXC7ruUCp1Z
3) You invest from that Bitcoin address to the escrow address. Keep in mind that you will get the tokens on that
Bitcoin address that you've invested from. This means that you must not use an exchange or web wallet!
