Puzzle 120 was redeem on February 27, 2023 (anyone can check it)
I have some interesting findings.
The priv. key shared by @RetiredCoder ( b10f22572c497a836ea187f2e1fc23) which is unlock the puzzle 120.
and this also used by ethereum wallet of the same priv key , that wallet was used 888 days ago it was June 8, 2022.
