Yes, Proof of Brain and DCC communities are great. For POB you need to write quality articles, creative works etc provided you can evidence use of brain. If you write from the front end proofofbrain.blog or proofofbrain.io then you will earn POB curation rewards too from community upvotes. If you post from other front ends, you can still tag #proofofbrain so that your post appears in POB community and receive community exposure. DCC is slightly different as it is a token to reward collaboration efforts between platform users. If you are collaborating with someone else on a Hive project or article etc or notice another worthy collab, then you can use the dcc cooperation tags to alert @clixmoney to the project and drop him a little comment as to why you have used the tags, as I think this is always helpful. If they have been used correctly, DCC and clixmoney may reward you with a few dcc tokens. At present @clixmoney is running a series of spotlighting different communities and attributes, including weekly contests around those communities and attributes so I would urge everyone to get involved. Two great token choices @merit.ahama. !PIZZA
