What the creator should do is send 1 btc to me🤣...
Seriously speaking, the creator must reveal the solved puzzles that were emptied, because what do we know if, for example, the puzzles are not in the range we believe? If he had a mistake when creating 256 puzzles (he corrected it, years later), he could having made the mistake of putting some keys in other ranges, or worse still it could be a big joke and he himself has emptied the last unrevealed puzzles to buy a Ferrari🤪.
Given that keys for ranges 1 to 65 and 70,75,80,85,90,95,100,105,110,115 were found in the intended ranges, the chances of any error on behalf of the creator are nearly zero. Now coming to puzzle 120, we see that the coins associated with BCH and BTG have not been moved yet (since 8 months) which makes it a bit suspicious. Whoever found keys 120 and 125 is either too rich to bother about the other coins or intentionally left the coins for others to keep working.
