Honestly 3 to 4k sat daily from just one faucetgame isn't bad at all, especially considering it's more or less a passive income once you get those upgrades.
The problem is actually getting all upgrades so you can reach that kind of income in the first place though.

I've been at it for over 2 months and I'm not even halfway done with my upgrades so I can definately see why most would give up after a few tries.
