Do you have any proof of sending 50k to mtgox? This is not speculation is throwing money off the window. You might win, but still it's stupid to do.

Did you make that deposit today and got it in instantly?
Yes I made this today and it should arrive tomorrow based on my previous transactions. It takes about 1 business day for money to arrive.
Well done. You will probably buy more than 500 BTC with that amount.. If Gox can pull their shit together you will be looking at a huge instant profit.
In other news: my concern is not Gox being insolvent "because they lost the coins". My concerns is they are in VERY deep shit for various reasons and funds might be stuck in there for very long.
EUR withdrawals still worked you say? Only smallish ones and VERY slowly. When it takes 6 weeks to process a fiat withdrawal, then something VERY bad is happening. I mean... If I tell to my bank to do a 300k transfer, they do it immediately, and in max. 2/3 days the money arrives to the account where I sent it. If they have to wait WEEKS to be able to send the money, then there is a serious problem somewhere. They won't tell us what is the problem and they make up BS excuses about their "huge volume" overwhelming the banks. In my book, that's very worrying.
