If your's is a fairly new Google Ads account, then the above would NOWADAYS most probably result in an account suspension.
Think from Google Ads algorithms "point of view". Google Ads algorithm will "think" : "Hey !!! This is a new advertiser and his campaign hence does not have enough of traction / data for him to do any analysis for him to just do an (auto) increase of 5% EVERY HOUR, this look pretty suspicious, so let us suspend this account".
And, also in reality, do you think a legit advertiser selling a legit product (or service) would actually set an auto increase of budget by 5% EVERY HOUR ???.
Google Ads churners and burners like us would ideally want a nice high budget even in a new Google Ads account. Seasoned blackhatters have their ways of setting a chunky daily budget in a new Google Ads account, right from the start. It requires creativity combined with experience.
But, do that safely without raising a suspicion in the "eyes" of the algorithms of Google Ads.
In other words, such actions which indeed appear suspicious to the algorithms of Google Ads, better be avoided, in order to remain on a safer side, especially nowadays.

EDITED to reply to the below ↓ question of

In a new Google Ads account, to remain on a safer side, ideally start a campaign with less than US$20 daily budget and after 2 to 3 days, set an auto daily budget increase of 12% to 15%. Do not make too many changes too fast to a campaign or to the Google Ads account, to remain on a safer side.
As you become seasoned & experienced, then if you add creativity to this part, you may get to imagine how seasoned blackhatters do this part.
