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.
I agree when you expect the favored team always to win every match because they have every advantage on their side but still manage to lose. The same thing happened to me when i was on a hot winning streak i started with 0.01 then ended up at 0.3 at some point then went huge on warriors to win the finals. I just suck it all up and move on with life.
