I'm in cryptocurrency space for one years already and I am thinking of possible ways I could contribute to bitcoin and crypto community, I realized that we have different line of track in where we try to improve ourselves, our skills, and knowledge for us to create or do something useful.
In terms of bitcoin adoption, people could wear shirts with bitcoin logo, tell their friends about bitcoin, and sell items through bitcoin or altcoin. I've just researching and learning how to code and I've tried to develop a system (Point of sale) for a small business located in our area but with a twist, it might be easy.
