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 ? 
Here in my country, we have few merchants that accepted Bitcoin which is coins.ph some are Coffee Shop such as Starbucks but not all their outlet accepting it maybe the franchising outlet only, some are Bar and Restaurant too. But when it comes to any gadgets, and department store were not in that stage yet.
