I tried to recoup 0.05BTC that I lost. I ended up losing 0.07 more on bitcoin. That was pretty much all the bitcoins I had so I've never gambled since.
I wanted to do the same once, I deposited 0.2BTC (was worth around $50 at the moment), and I wanted to go all in. I don't know how but I managed to get back 0.25BTC, I withdrew and never deposited again since. Bad decision to take, you can risk all of it so easy...
Good for you that you managed to chased your losses and wise decision when you won something and withdrew as soon as possible. Sometimes it's really hard to chase your losses with a mix emotions if you're really desperate to take back of what you loss. You can risk all but it's hard to predict the result.
