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.
There are some people that would be like you, of course I agree. Then what are about those that are unlike you who uses 5 to 10x of your 1% as bankroll to gamble. If they have to go all in with such X amounts at a go, what will you call that?
EG: If I earn $5k monthly and am using 10% of my monthly income as my bankroll, that would be $500 and let say I had to use it all at once to gamble. That means am going to wait till the next month to gamble again, isn't it? What's the prospect or how likely is it that the gambler can hold on till next month without having to go beyond his bankroll.
You or someone else too may not agree with my thoughts but am still of the opinion that going all in with our bankroll encourages the chances of irresponsible gambling.
