Hey everyone, just stumbled upon this wild Bitcoin puzzle. Apparently there's almost 33 BTC up for grabs for anyone who can crack it.
The Bitcoin Puzzle: Who's Got the Keys to 32 BTC?

Found this funky transaction while poking around: it's got some serious mystery going on. Multiple addresses involved, all with keys generated from a formula... what does it mean?

Yeah I saw that too. The amounts sent are odd, increasing from like 0.001 up to 0.256 for each address. What's the deal?

I'm getting scam vibes too. A newbie tossing over 12 grand for some number puzzle? Seems sketchy.
Who's behind this anyway? Anyone know the creator? And how do we even start calculating those private key values?

More details on the PVK values for the addresses would be handy. Like, what are their decimal and hex values?
Wait, so you thought it was the OP offering the reward? Then who actually is?
Not sure who created this. I just found this transaction while messing with my bot. Lots of addresses with patterns... it's tempting to figure it out.

It does seem pretty easy to crack, right? But why's the reward so high?
The transaction leads back to a massive address with over 56K BTC received. Definitely a big player behind this.
Good catch on that. That address is active too, doing transactions daily. An exchange maybe?

Nah, this ain't easy. I'm not even close to solving it yet.

Right? I still can’t wrap my head around how to solve this puzzle. Suggestions?
I see some patterns but doubt they help much. My guess is each BTC amount indicates a bit length in the private key. Like, 0.001 BTC = 1 bit key?

Thinking brute force is the only way. Starting at around 607809, multiply by 1.7, convert to hex, create addresses, and check them. Sounds tedious.
Guys, before you post here, really read through everything first. We don’t need random off-topic rants.

So there’s no real pattern? Are we just looking at it getting tougher as we go? Maybe we need some GPU power.
What’s the best tool to brute force this puzzle while we brainstorm? We need to hit this from all angles.

A GPU bot would be ideal for brute force. I’d code one, but I'm not feeling it right now. Anyone else got skills?
That’s why I posted, I bet there’s already a tool out there for this.
