Guys, here's a new puzzle challenge from the channel https://www.youtube.com/watch?v=LkejrZuQadg, this challenge consists of locating the private key of the address 19L9vivFCPJnAVDsjZ76mF2ZiTLKFUXEpV which is in the same range as puzzle 66, but with a dot , according to the creator, next Friday, he will request a transfer, the objective would be to export the public key on the blockchain and test whether it would be possible for someone to intercept the transfer before it is completed through the RBF, thus removing doubts whether The same thing could happen with puzzle 66, so whoever has the BOTs being heated could do this test with this key. hahahaha.

Anyway, you already know the day, you just need to be more agile than the process on the blockchain, according to the creator, he will place the transaction at the lowest possible rate, precisely to understand if it would be possible for someone to intercept this transaction and withdraw before him, good luck.
