I was really into the 1,000 Bitcoin Challenge where they picked keys from a range of 2^n < x < 2^m and those held a specific amount of Bitcoin in their wallets.
Now that that one's all wrapped up and with Puzzle #71 currently going (which apparently would take like a century to solve at current rates), why not set up something similar on a Bitcoin sister-chain?
I don’t have the private keys for any of the addresses except for the 3PUZZLE addresses (and they’re not rewards yet, I just sent some coins there to make it look cooler). I grabbed these addresses using privatekeys.pw and went through the possible addresses from Puzzle N, so clicking on Puzzle 30 was supposed to get me an address in that range between 2^29 and 2^30...
Here are some addresses I found:
