Bitcoin is just a virtual currency, but it is used as real money to buy many things. There are many people who accept Bitcoin payments for items, including online stores and regular stores. Popular online stores accept Bitcoins including Newegg, Overstock, Microsoft, Dell and more.
In the United States, there are Reeds Jewelers, One Shot Hotels, Holiday Inn, and even pizza locations, restaurants and more. You can even use Bitcoin to buy addictive drugs, gambling, bullion, or even donate to charity. This is the reason why I like BTC.
That's absolutely righ. Fact is that, you can now buy more thing unlike before because the market value of Bitcoin at this moment is way higher than its market price 5 years before. But since its value is expected to be more expensive in the future, you may obviously buy more things from it when its value starts to rise again. And in a line with that, transactions are decentralized so I am hoping that it won't be involved on illegal things.
