As much as I like your work, I still want to say that Im not the type of person that go around wearing a shirt with Bitcoin logo on it or with any description or something that has to do with Bitcoin. This is probably a waste of time. It will be best for you to open an offline shop where you will be designing shops or. Something and getting paid. I also know some sites online where people get paid for designing T-shirts, but thats if yours is chosen.
You may be right but the fact is if you are there in the world of the digital currencies and that you want the things to be in your favor, then you must play your part and that you need to make more people aware of this crypto currency and that you must encourage them to use the crypto currencies and to invest their money into it. Wearing of the bitcoin T-shirts is the best thing one can ever do.
Making bitcoin T SHIRT is a good idea, and it can be proven as a source to promote or advertise bitcoin to the community, because as when we will get this t-shirt and we will wear an amazing shirt will be the center of attention for people of my community, so this way people will feel attraction for is and they will ask you what it is motif of this logo so this way bitcoin will get famous day by day so I really loves the idea.
