Facebook ads are pointless unless you have minimum of £5k per month to spend

Just throwing this out there—are Facebook ads even worth it if you’re not spending at least £5,000 a month? It feels like anything less doesn’t generate enough data to optimise properly, and the results end up being either too slow or too inconsistent to make it worthwhile.

It seems like without that higher budget, you’re just throwing money into the void. Anyone had success with a smaller ad spend?
