I agree, almost everything can buy using bitcoin as long as it is legal in each country. But with the situation of price of it on the market, it is doubtful to use it for purchasing but rather invest it to grow some more. Not only product can pay by bitcoin but also services.
Just holding to the right time, You bought now and exchange it when price enough for purchase product some thing. Spesific product have to exchange it into bitcoin, at other country with seller accepted bitcoin have alot of product to sell not only service.
