This is nice suggestion and this business is gonna be successful because more people will buy it and will hold it, bitcoin will be the best service and it will be the most advantageous way of promoting bitcoin in the world so I am agree with you that bitcoin will get more famous after, because of that nice logo at the center and the good stuff people are going to love it.
Yeah no doubt it is new business idea and you can also promote bitcoin by this way. Young boys and girls are fond of new design in shirts. You will make good profit in this business. On the whole bitcoin T-shirts will be the way to prevail bitcoin in the globe easily and those who do not know about bitcoin will ask about this and thus by investing the market cap will grow.
