Hello everyone! It just occurred to us that the fifth anniversary of primecoin is approaching, and we’d like to hold a game to celebrate it!

Since primecoin is about prime numbers, Cunningham chains in particular, it would be a good idea to guess prime numbers. Maybe the numbers in the next block after the anniversary (18UCT 7th July to my memory)?

What do you think? I can donate like 300 coins for prize.

(This thread is continuing Anyone still maintaining Primecoin?)
