That's right to name a few; however, depending on the locality and where you're in, Bitcoin can be used to pay for goods and services, sometimes, like any other currency in the market. I think the difference with Bitcoin and other digitally converted currency or medium is the fact that people choose not to use it that way. Right now, if you would use Bitcoin or cryptocurrency as any currency out there, then it would be the weakest and simplest way to use it, which in turn, would not serve it's currency purpose, which is as an investment medium. I mean, why would you use it that way, when you can use it to work for you.
