user9114: I did a bitcoin transaction of 216 BTC from the 50BTC mining-pool to my wallet (Bitcoin-Qt).
It has been 3 days now and I have not received anything yet.
I've tried to search my address on blockchain.info and it doesn't come up.

user9320: If you look on the Mining page at 50BTC, you will be able to see how many coins you have actually earned in their pool (because, as Yngve mentioned, 50BTC was hacked at the end of October, so the account balances are inaccurate).
By subtracting the number of coins that have been paid to your payout address (use a service like Blockchain.info), you should be able to determine exactly what is owed.
I have reached out to them a number of times because I'm still owed 7.4 BTC and have had no response yet. Best of luck to you; let me know if they reach out to you!

user9289: 50btc was hacked some time ago and the hacker completely messed up all account balances. If you actually have mined over 200 BTC there, I suggest you contact the administrators. But I assume you're just one of the people who woke up one day and saw that your 0.001 mining profit had been replaced with a completely arbitrary number of coins, in which case no, "your" Bitcoins were not lost since they never existed in the first place.
