So everyone here are talking about how we can use Bitcoin as the new world currency, but wait a minute. How can you use bitcoin in your daily life when it's so volatile?
I'm not talking about exchange trades or investments, or any way to make a profit out of it speculating but for example if you want to go out and buy one coffee with bitcoin or just do the groceries, compared to your local currencies it will be almost impossible to know what you gonna pay for it.  Of course if you switch only to bitcoins it won't matter and if you get your salary in bitcoins and everywhere you can pay with fixed bitcoin prices and you don't pay attention to the outer currencies but to reach to this level it is almost impossible for me to imagine how we can implement it in our lives. For now it is just an investment /quick profit tool.
