Is $10 a day enough for Google Ads?
For most competitive commercial keywords in the US, $10/day (~$300/mo) is below the threshold where Google's automated bidding has enough conversion data to optimize. You'll get some traffic but the campaigns will spin their wheels in "learning mode" indefinitely. Practical minimum for a real test is $30–$100/day depending on category; higher for legal, insurance, home services.
