I believe we're coming towards the end of the stealth phase, crypto is starting to get mainstream to an extent. But I believe it's still in its infancy, there are a lot of problems to be worked out before mass adoption is possible. Crypto currency is still far too advanced to be understood easily without a good deal of research as to how things work, and transaction fees will have to come down drastically for bitcoin to be used for day to day small purchases. Litecoin is a great alternative but is not as widely accepted as Bitcoin is. I think by 2020 cryptocurrency will explode and we will start taking off. All I know for sure is I'm excited to see where all of this goes in the coming years.
