I've use bitcoin to buy computers, gold, silver, and various collectibles on this forum. It is very useful if you know how to spend it.
I spend my bitcoin to buy gadgets to use to my work in bitcoin like computers and phone and advance payments in my internet and also I buy the things that I used in everyday life. Before I buy the things I needed to ask my self if I really need it cause I want to spend my bitcoin in only important things.
