Multiple ads are profitable early with 2.5€ each one — too soon to scale?

I have a campaign for a product where several ads are generating sales within the first few hours, with only a 2.50€/day budget per ad.

What is the best way to scale this?

Or is it simply still too early to scale?

However, more than one ad is working and generating sales.

Does that indicate something meaningful?

Could this be a sign that I have multiple winning creatives, or is it still too early to make any scaling decisions – even if there are several ads making sales?

Thanks!
