I think the end address belongs to some market as their wallet showed some 36mil dollars worth of BTC and there my BTC sits, but what is the place...
It was 24. of last month about 16.24 GMT+2 time. I transferred the funds myself but I don't just remember where... I've checked some where the funds were not, now I would look some where it is =)
What do you know about this address: did you store it in your wallet's address book for some reason? Can you tell when? Did you attach a label at all?
Where might it have come from: what markets, exchanges, stores, etc. have you looked at in the time period where you might have found this address?
How many BTC are there?
