Personally, I find it really useful to post on Splinterlands Social Media Challenge, I earned around 91 Hive (divided into Hive Power and HBD) as a reward last month, it is a bit more than a dollar per day but I have to say I have been lucky because I received some nice upvotes recently.

So just comment on: https://www.splintertalk.io/@splinterlands/splinterlands-weekly-curation-challange-december-27-2021

Share your post on your social media of choice (like Twitter), using #splinterlands and #play2earn tags, and if your post is well written you will be upvoted by Splinterland's curators.
You can post twice a week on the Social Media Challenge and enjoy the rewards.

It is really useful to use the hashtags #spt and #splinterlands, other useful hashtags are #oneup and #pizza (to receive small tips).

So to sum up: publish nice posts twice a week, share them on the Social Challenge and use the right hashtags, and some nice rewards will come.

I hope it is useful for everybody who will read this comment.

Happy new year :)
