It's a very nice development for a person to design his own T-shirt, not a expensive price of 20 dollar, but it caught my attention; Why is not Bitcoin paying?
Making bitcoin shirts is a good idea and can be made as an advertisement or promotion to introduce bitcoin to the community, because when we wear bitcoin-patterned shirts will be the center of attention or when people see bitcoin-patterned shirts people will see and will ask what is the meaning of the shirt motif and most importantly for as good as possible the motive of the picture so that people see it and attract attention. if people ask about t-shirts we wear bitcoin we just explain the meaning of bitcoin and its advantages so they understand and join join.
