I am seeing 2 scenarios.
1. Bitcoin forks unsuccessfully, causes alot of things to go wrong.
2. In 2016, lots of banks are integrated, and the next pump happens with banks, licenses, and regulation in place. And we see $2k-3k
And now imagine, regular people going to a bank not to buy bonds but to order a few bitcoins for their retirement account.
I actually see this happening, but it will probably be rather young people that grow up with Bitcoin. I don't see 40 year+ olds of today doing that, they are simply too much out of the loop in average, except the ones that are into BTC already which are probably posting in this forum.
