Crack my BTC wallet, earn 1000 USD

Hello everyone,

I'm not proud of myself but here I am.

I installed bitcoin core some months ago just to give it a try. I didn't remembered there was a key on it as it was never asked when the Bitcoin client is launched.

But I received some coins on it and when I tried to do a transaction myself it asked for that damn key and I understood my mistake
It looks like I didn't write the password somewhere, what I was thinking ? I don't know

I tried every passwords in my password manager and tried some other passphrases that I could have used but none worked.

I don't even know if I used a shitty password (I tried rockyou though) or a longer passphrase.

I have only CPUs at home that's why I'm asking for help, it will take me way to much time to crack it.

I will give 0.15 BTC (currently a little more than 1000 USD) to the first person able to crack the hash. Reward will stay at 0.15 BTC whatever the value of bitcoin.

Here is the hash :


I didn't find any suitable section in the forum so sorry to disturb
