Do you think someone was testing out MARA or something on this address next to the puzzle first before attempting the puzzle 67's sweep?
Interesting find. But no, this wallet was first used 2 days after 67 was found, and wasn't mined by Mara. Probably just someone messing around or doing some other testing.
