I'd like to put this offer on the table:
1 ESP for 1/2 of 1 satoshi.
So for example instead of 100,000,000 = 1 BTC, I'd like to offer 200,000,000 = 1 BTC
Just simple trust. You can call me on the phone, take my address down, add me on facebook, find me on twitter, while doing this.
I have 500,000,000 ESPER and will accept 2.5 BTC for it. So even if you sold it at 1 satoshi, you'll have doubled your profit.

All that for 2.5 BTC.
