Sure. Definitely Bitcoins. We will create manual system to credit ANK for Bitcoin, Ripple, Dash and other large coins. We've done this due to popular demand and the diffficulties of getting ETH for some people.

If you have BTC or any other crypto in the top 10 and don't want to miss out on the whitelist. (Its getting filled quickly!), then fill the form out but put:
Contribution Amount :  BTC/DASH/Ripple/etc... {xxxxx amount}  (please pick 1 coin)

I also suggest sending an email to me craig@ankorus.org though this isnt mandatory. The reason other cryptos are more difficult to collect is because the smart contract itself converts ETH to ANK, whereas with BTC we need to manually do it for each person.
