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🤪.
