My biggest win was at Bitstarz Casino 3 or 4 years ago.
I deposited 0.2 BTC and won 11BTC.
The BTC price at this time was arround 450$.
I played in the following weeks and months at the same casino and lost all of my winnings.

Wow!
11BTC! That's a lot of Bitcoin.
I doubt if it's possible to win this amount in recent gambling sites. I guess its because BTC price was low them. One will be damn lucky if they are able to win 2BTC in one game at a stretch.
I would have given it a long break before playing again if I were you; they indirectly collected back the winnings

That's a lot of BTC but just a small amount since that was 4 years ago.
Now, it's different, I don't even a typical gambler would be willing to risk a whole BTC for gambling because that's equivalent to $10,000 already.
Things are different in the past, if he was able to keep his BTC until now, that 11 BTC might change his life, well, for me, it will change for sure since 11 BTC is equivalent to $110,000, and I'll become a millionaire if converted in our local currency.
