I'd try Web3 vs Web2, mostly Hive vs Facebook. The 5-second hook can show someone scrolling through Facebook, where he'd waste time for nothing, then suddenly cut to Hive with a similar vision, where his time will be converted into money.
I'm having a tough time right now, but if I get enough time soon, I'll try to make a real ad of that kind. I'll do all the editing and probably the acting as well.
