Well, yesterday was the end of the Prom Zealy Sprint campaign and I'm happy to report that I'm getting a $250 airdrop reward.
I believe it was a worthwhile investment of my time.
The campaign involved typical tasks associated with Zealy: following Twitter accounts of various Prom Ecosystem projects, liking and reposting their tweets, and occasionally installing their apps.
Although there were over 100 tasks, most required only about 5 seconds to complete.

In total, I spent no more than 4 hours on these tasks.
Admittedly, they weren't the most exciting hours of my life, but they certainly paid well – roughly "$60 an hour," which is quite good considering it required minimal skill and effort.

The total prize pool was $10,000 in $PROM tokens.
While not everyone earned hundreds of dollars, even making $30-$50-$100 was a decent reward.
With the campaign lasting 30 days, there was ample opportunity for anyone interested to participate and potentially succeed.
