Google Ads algorithms are often on steroids mode. So, a drastic increase in daily budget, can trigger an account suspension and weirdly, sometimes a account suspension due to that will mention as due to circumventing systems !!!
AND, too many changes done too fast, also can sometimes trigger an account suspension and weirdly, sometimes a account suspension due to that will mention as due to circumventing systems !!!
Nonetheless, pertaining to increase of daily budget, a safe or safer way to increase daily budget, is by using the automated rules option, see
Set up automated rules and
Common ways to use automated rules. Set an automated rule to auto-incease daily budget by X% (a safe bet here, is usually a setting of 10% to 15% for auto-increase of daily budget, setup as an automated rule).
Do not make too many changes too fast, on a campaign, to be on a safer side. If you want to make for example, 3 changes, a safer way, is to make 1 change per 24 hours (to be on a safer side).
DISCLAIMER : Those who want to make or claim to make a trillion changes to a campaign, all within 30 seconds, let them do so and let them be happy. The information that I have provided in this reply of mine, is aimed towards a better chance of success. Handle every Google Ads account and every Google Ads campaign, just like you would handle a small baby.
