Depends on how much is present on my account in a single instance. Most of the time, I'm confident on my picks and go ballsy and place a 1 btc bet only to win afterwards. I've lost 0.6 once on MLB betting. It was Rangers vs Yankees. I couldn't care less though, because 0.6 is kind of big, but after a short while I got by with it and accepted it.
Being too confident in gambling costs a lot sometimes, when your confidence snatches all your bitcoins at once then you realize that you were over confidence and that is the reason why you lost everything you had in your account.
However, he gambling with big money. So if he is a good in predicting for sport, he can be winning a lot and 0.6btc is just a small % overall of his bankroll. You can expected someone to win 100% so maybe this is just a case that he has lost and he may have won a lot more from the other bets.
I think even if you're having a defeat that only a few percent of your total bankroll but 0.6 is a huge amount for most people. and I think you can not underestimate it. let alone to Obtain 0.6 BTC is hard for me. I think any amount of Defeat will make-your slightest Become chaotic and disorganized play
