Bitcoin will go mainstream surely as the change has already begun.We can not just see the speed of change it is much more faster than we imagine.It is inevitable now as lot of the water has flown under the bridges.Governments as well as bankers are failed to stop Bitcoin in last couple of years.A totally new era of financial freedom and privacy is to come soon.
Totally agreeable although there is nobody stopping anybody from scare mongering with the kind of dark services that can be purchased with BTC. Despite this, I do think that BTC could potentially go mainstream but this is ultimately dependent on the faith of the general public in it. Personally I feel like not enough people are aware of this financial freedom that can be easily achieved.
