you could have to hit a button to load the captcha to enter it that wouldn't reduce security any and still make my suggestion viable also a timed out captcha just loads the page again without activating the timer so even that's not necessary
Ok.
But you do understand you want to cheat the system? Possibly you're not even aware of it but that's how this is going to end, I shall give you an example.
Example (real time application):
My current upgrades are so placed that when I enter a captcha,
I MINE FOR 130MIN.
Apply your suggestion would mean I enter the captcha, wait for the timer to show op and re-enter the captcha once again for the next period.
1MIN online time on the site would result in me being able to MINE FOR +4HOURS.
People would just rape the shit out of the chambers and the site its flow would be disturbed
