I think the goal is very worthy, and also interested in promoting cryonics. But why tie it to a particular highly speculative currency? I don't have any advantage as a currency trader.
They both fall under the category of a highly underestimated long bets in my mind. Bitcoin's recent rise in value vindicates my earlier speculative feelings and makes me wish I had listened to them more consistently (not selling out my personal stock, e.g.). So I should be more confident associating it with cryonics than I was before.
If you think of them as simple independent variables, success for both cryonics and bitcoin would appear a less probable conjunction than success for either cryonics or bitcoin. However popularity can drive technology and vice...
The bitcoins that I had set aside for a Cryonics contest two years ago (and were unredeemed) are suddenly worth a lot more.
Details: I had added 10 bitcoins to get things started, and there were 4.75 worth of additional donations. These were partially lost when the hosted online wallet that I was using (MyBitcoin) was hacked, but 49% was recovered. As of today, after refunding part of the donated money, it is now worth 5.2675. I will be adding from my personal store to bring it up to an even 5.5. At $140 per coin, the new total is $770.
I've decided to follow the buy-and-hold strategy for at least another year, since it worked so well. I don't have exact details on what I'll do with it, but it will not be converted or spent for at least one year, and will eventually be used for promoting cryonics in some way.
Some things I have in mind if it gets big include:
