Indeed, bitcoin is difficult to be adopted as a conventional currency. But a number of potential innovations such as Lightning Network that use bitcoin or Visa-based LitePay litecoin transaction services can make virtual currencies act like conventional currencies.
Is that still not enough to be called a currency?
I think it's more than enough to prove that bitcoin is a currency or a valuable coin.
Just in case that your mindset towards bitcoin is bad well my friend I'm encouraging you to start changing it. You must have a proper mindset in this system so that in return it willis be good to you. It's about time to think properly and have a better living. The battle indeed is really in your mindset so I suggest you to cleanse it.
