Bitcoin has had its time.
Losing capital really fast now and no signs of recovery.
Technical capacity is not there.
Community support is not there.
Media support is not there.
Economic support is not there.
So many altcoins that solve the problems of this giant cluster f*ck that is Bitcoin Core.
We may very well be entering a long term bear market, but even so, I don't think it's because of the bolded part. Everything is down, and some are even struggling harder than Bitcoin. If Bitcoin Core were the problem and alts were the solution, we should be seeing Bitcoin sliding with alts surging (granted, that happened some weeks ago, with Ripple surging, then Ethereum surging).
I'm not calling it quits with Bitcoin just yet.
