I like participating in the CryptoU Challenges but many colleagues are intimidated to even start.
Since we use everyday our internal communication tool, we see each other mostly virtually through our profile picture. I think a great way to advertise CryptoU Challenges and to have more colleagues join in is to create a badge to put on top of our profile pic once we complete the latest challenge.
To me, completing these tasks is a badge of honour and my reward NFTs can only be shown around if someone asks... There is certainly a way to brag more about being part of the CryptoU community!
