Hello friend @yoelmo26..
The SEC to me is one of the best thing that has been introduced into this platform so far. It has sincerely increase the participation and engagement of users in various communities with support and reward for doing so. The team has been doing a lot to keep this initiative going through.
Wow I must say you are very active to the extent of participating in so much engagement challenge every week just as you mentioned in your publication with proof of screenshots. Well as for me I barely participate in at least 3 of the topics presented every week....

The engagement challenge has made a great impact on the platform as users get to increase their reputation, steem power and also gain rewards...

Individually this initiative has also brought more interest in me on creating content on this platform despite the highs and lows..

Thanks for sharing and good luck with the challenge...
