We got robbed of Puzzle 69.

Hello, we are coming out to claim we are the group that solved puzzle 69.
We are a group consisting of 12 software developers in Asia with interest in cryptography. We have been scanning puzzle 66, 67, 68 and 69 since last year.

We have rented several GPUs online to use for the puzzles. Unfortunately, puzzle 66 was solved by

1Jvv4yWkE9MhbuwGUoqFYzDjRVQHaLWuJd (not us)

but got stolen using RBF. Puzzles 67 and 68 were solved by 1 person and then finally we were able to solve puzzle 69.


We are using our custom software written using CUDA C++. Each member has several GPUs which will be given a range to scan. It was really a eureka moment when we were notified that a match was found by one of our members.

We are aware of RBF attack so we used a wallet software (we prefer not to say which one) which does not enable RBF by default, to transfer the coins. But when we checked the transaction, before it was confirmed, another transaction was created.

This is really heartbreaking for me and my group because we spent months scanning the range only for it to be stolen by others. We are contributing part of our savings to pay our GPU bills monthly. We might resort to contacting the wallet software provider but we know that our 6.9 BTC is long gone forever.

Now, our problem is how to pay our remaining GPU bill which amounts to $158,954.07. This is so frustrating! Why can't people play fair and square???

We are accepting donations to help us pay our remaining GPU bill in these addresses:
