The most expensive thing that i bought in bitcoin is my laptop that i used in my study now actually not bitcoin. I exchange my bitcoin in my country money but not all bitcoin i exchange in money i'll just exchange the bitcoin in money that required only to buy my laptop now i'll used my laptop not only as in my studies i'll used this to be updated in bitcoin and joining the campaign. Now i don't need to rent in the computer shop just to be updated and joining the campaign i'll used it anytime and anywhere. Thanks to bitcoin
