I'm afraid you made a bad financial decision. You will lose many users. Few will see your ads, and your advertising revenue will be low.
In my neighborhood, many have done it. Everyone now stopped.
I actually think I've done a good financial decision by simply adding one extra step before users can earn a lot of coins.
Cryptoracers was one of my highest paying sites. It was paying $2k per month. No one was racing. Can you spot the irony? Crypto"Racing"?
You'll neighborhood will survive, I don't doubt this.
