If BTC will fail, it will be very hard for people to trust again on alts.
It won't be a quick and one time event, it will fade slowly, with capital gradually (over the course of 2-3 years) flowing into a small number of alts with unique and prominent features. The capital flow already started by the way in 2014.
Please demonstrate. Is there a youtube video that shows these "unique and prominent features" in action?
There is absolutely nothing under the radar treatening Bitcoin's position. This guy is delusional and probably trying to trigger more weak hands.
