A small mistake on dice made my wallet get emptied. Only mistake is that I didn't added an additional zero to the bet amount. Instead of 0.00005 btc I mistakenly placed 0.0005 btc. Further on the consecutive bets went for a double the value. This all of the sudden emptied my wallet. I didn't watched the wallet until the bet amount in the tab turned zero. Further watched the bet history and understood what big mistake I've done.
Not only on gambling but also on sending funds, on trading and so many actions that require transacting if you have problem with your eyes, be sure that you are on a good condition, not feeling feverish or drunk, but ever that happens and the amount is big then you will learn your lesson and you see to it that it will never happen again.
