When will cryptocurrency go mainstream?

Although cryptocurrencies are slowly being used by more people and accepted by more vendors year by year, they are still not mainstream yet. Cryptocurrencies will only truly go mainstream when their price stops being so volatile and when it is easier to keep the currency safe from theft. It will be at that time that mass adoption will occur by consumers, vendors and financial institutions. This will make cryptocurrencies a mainstream currency to compete head-to-head with fiat currencies in every way. 2019 COULD be that breakout year…. Or it could still be many years away.
