I've never clicked/used the MAX becasue that would scare the shit out of me, so I'm guessing here, it depends on how the process has been programmed.
If (a) it sends to the server "I want to use the MAX" and then the amount is fetched server side or (b) it sends the exact amount itself as previewed in the input box.
(a) If it sends "I want to use the MAX" you might have been credited the Manchester winning right between the timeframe you clicked the MAX button and the instant the data reached the server and it was processed, so at that time it processed the MAX including the Manchester winning.
If it works this way you may have been very unlucky.
(b) If it sends the exact amount as it has been put by clicking the MAX button there couldn't be any misinterpretation on what happens server side. If it works this other way, the 0.04xx BTC amount was put in the box and you didn't notice because maybe the Manchester winning was just been credited to your account.
Here you must be honest with you: did you double check the sum you were betting before clicking the submit button - that might have been 0.04x BTC because it was just the winning being credited - or rather having done that same action hundreds of time you skipped the check part and went straight to the bet button?
Yeah I am sure that it is not ~0.0X BTC.
I doubt that the webpage showed ~0.00000XXX BTC but the server gave all amount including the reward from match betting.
TheQuin also said here, "This is what I just answered above. When you click max you get a popup saying "Are you sure you wish to bet the maximum amount? Click OK if you would like to proceed else click CANCEL.". At this point, the input box still shows your last input or the default 1 Sat because the max value is only filled in if/when you click OK. Then after the amount is filled in you still have to enter all the other roll parameters and then either click BET HI or BET LO".
However, the problem is how much the server had fetched actually for my bet amount
after I pressed "MAX", even the webpage showed how much I was going to bet.
"TheQuin" keeps sending on the situation of "the webpage will have pop-up reminder
when you pressed "MAX" and this is not the main point.
I just think it is my fault because I am not good at explanation.
As you said, maybe I am unlucky because the server fetched ~0.0X BTC "secretly" though I had made sure again - it was ~0.00000XXX BTC but not ~0.0X BTC.
A lesson to me - do not press the max button if you have large amount on your account.
