Ads is another different and best way to advertise creative work. through ads people who are not aware of the existence of #proofofbrain will get to know more about it, if #proofofbrain is to be advertise through ads. Am very sure there could be more ways but that is all I could think of and I think is a good idea and answer for your question..
Good morning all🙋‍♀️
