Airdrops are no longer a thing in 2025.
And CEX.IO doesn't have the hype like it was 2018 if I'm not mistaken. So don't be surprised though, they might have been late by 7 years, lol. It started with Binance and so with that since they are the prime mover, then like Bitcoin, they will remain on top of the league.
Powertap? Or simply tap to earn? it was the hype at the start of the year and soon died down as well.
There are still people earning with airdrops, but its not the same as before on where they spend less time since now they need to exert effort just to qualify. But earning chance is so less so that's why much better not to participate since most likely they won't earn with scam airdrops now.
That power tap thing they participate? the hype didn't take long since most of projects copy that concept turn to be a scam.
Better to spend time on other things since there are lot of challenging also rewarding activities they can find on crypto space.
