In my opinion it's even an act of irresponsible gambling behaviour that I should go all in with what's in my account when I could gradually make the most part with each session.
It is not irresponsible gambling. What that determines irresponsible gambling is the amount of moey that you are using to gamble. I gamble with just 1% of my weekly income and not often. But there are sometime I can visit Stake and use the 1% if my weekly income to gamble at once. I think there are some people that will be like me.
