Use these DAI set up bounty projects or recruit more developers to accelerate the development of HOPR.
Some people says buy back and burn HOPR token to raise the price. 168,763 DAI is insignificant for liquidity, but it should be enough to attract some developers. The best and direct way to do this is HOPR more practicable. HOPR Mainnet launch earlier HOPR token to the moon earlier. Mature products are the best marketing. This will benefit to all node runners and stakers.
I’ve created a proposal which points in a similar direction, might be of interest for you! 
Thanks for the proposal, @Samz! I marked your proposal as invalid, as we’d like a bit more specifics on the exact use of token, the benefit of your proposed measure and more in depth information on all in general.
