In some countries bitcoin cannot be use to buy Real stuffs like food clothes and other goods and services but even though bitcoin can be used in plenty of ways mostly in the cyberworld it is used in online markets like Game Credits, Gadgets some use it in the dark webs to purchase weeds,drugs. Others are trading it to a different crypto-currency or exchanging to dollars, so how to you use it ? 
I use it just how it could be used now. We have limited options in our country and most of it is just to exchange it to fiat.
Prepaid load is a good business here in our country considering people want something cheaper as always. Not much use the postpaid so my loading business is blooming. Add up the people who want to buy something online. They just go to me and ask a favor to buy it through bitcoin for they have no money online and cash on delivery is not available in the item that they are buying. I just add up some percentage whenever they want it as soon as possible.
