Offering 30,000 IOTA for 1 BTC, escrow by yassin54 as long as you and he agree to the terms:

By buying a 30K IOU for IOTA from me, you are taking part in the same risk I took part in when I sent BTC to the crowdsale address. This means in the unlikely event IOTA is never released in a working state, has serious technical flaws, or any other unforeseen circumstances result in the token being valueless or near valueless, I will be paid the 1 BTC so long as I have made every effort possible to send the 30,000 IOTA to your IOTA address.

If need be I can confirm I own my genesis IOTA address in private with yassin54.
