Exactly. It is the same story when people say "Facebook ads don't work" or whatever the new ad platform is. If you could simply hand $X to an ad company and reliably return $2X or even $1.2X then the money would simply not last because there would be no barriers to entry.

Customer acquisition is not something you can leave to chance, it would be like placing a bet a blackjack table and saying you better quit if you lose. If you dont know how to count cards, you should have quit before even sitting down. If you dont know how to utilize different ad channels, you are better off studying them before betting anything, otherwise you are just playing blind.

Find a repeatable way to profitably onboard customers. If you cannot do that and have truly put the effort in to understand the different channels, then it may be time to pivot. Otherwise, you are just gambling.
