50 days left to claim 3x$500 in bounties for Cuckoo Cycle proof-of-work

[tromp]

Since mid-2014,
  https://github.com/tromp/cuckoo
has offered bounties for disproving that Cuckoo Cycle,
my Proof-of-Work that spends most time on memory latency,
- has an optimal reference miner
- has no feasible memory-time trade-off
- offers no advantage for GPUs

These bounties are set to expire at the end of this year,
so get coding for a modest Xmas bonus!
