Ask HN: Unbreakable Crypto How to Market

I was talking to this tech person today who was telling me about his unbreakable crypto technology. He was wondering how to market the idea as it didn't get any tracktion in the market.

I was wondering if a social network type of approach where you offer an incentive (1000$) to break a technology, yet you have to pay 10$ to enter which get added to the amount offered. Is that something that could interest people to try to hack your crypto? Is that too cheap? Like bounty hunter on a bug?

Are there contest and other avenues to prove your working concept?
