-Can bitmarket-admin confirm, that he owes me 47,6258 bitcoins? (My username at bitmarket.eu is fluppisippi.)
Please note though that since Bitmarket is not a bank, we don't have any insurances against theft or other unpredicted losses of Bitcoin. While legally I don't think I own you any Bitcoins (as per mralbi said), I feel morally obliged to return them to all users that had them stolen, that's why you will receive them back after we gather necessary funds. They will get the same treatement as the "on hold" ones from the previous loss, possibly with one exception - they will be probably reimbursed first.
-To which bitcoinaddress(es) were the latest 620 stolen bitcoins sent? (Maybe bitmarket-admin already told us, but I could not find it)
As someone already said before, the address and all necessary information was already posted before. The address that was used for the theft is:
http://blockchain.info/pl/address/1Lbcfpaw3uHs3iarBqZ12FYeD5vFwNvY49Also, I don't really feel posting my postal address to some random guy on the internet, even if I owe virtual currency for him. Bitmarket investors will know my personal information and that's sufficient.
This might be relevant for people in the UK and other EU countries thinking about taking the previous owner to court you may not get all your coins back or their monetary value but if you just want to see him suffer the consequences of his actions it might be worth it:
I've reported him for fraud and theft this morning and I am awaiting a call from the police in the coming days to get more information from me.
