Re: ARG Puzzle with 3.5 BTC Private Key Prize

The code from Wow.jpg (z69JZqlJn862D1ndx7oLVEMmVolP1zewEeUCrsI7Roahzpeny7P) maps to the following numbers using the above character mapping:

Code:

61 6 9 19 35 52 47 19 49 8 6 2 13 1 49 39 59 7 50 21 31 14 22 48 31 50 47 25 1 61 40 58 14 40 30 12 53 54 18 7 27 50 36 43 61 51 40 49 60 7 25

Maybe to shift this by 64 to get ASCII characters?

No, that gives you a newline char which I don't think the OP would have used.
