Hi,
I have lost over 300BTC through theft and one 20 minute self destructive gambling spree in the last year or so.
Oh dear wow dude that is on the side extreme gambling most do not gamble nowhere near that, the most i have seen someone post who has lost was 650btc and now another 300btc that is crazy amounts to be putting into gambling sites.
Hope that does not get you to down and you can bounce back, i don't mean play and try and win but move on with your life and forget gambling because the feeling must suck.
Thanks for the warning for myself and others good luck with whatever you choose.
