I'd agree with this if bitcoin was still the only thing doing what it does.
It's old, and slow and expensive, and I dread using it.
Last transaction I did took 15 hours. I don't see it coming back from this dip, to be honest. The only advantage it had over a hundred grandchildren, (like STEEM) was it's relative stability.
I can see it drifting sideways, then tapering off until 10% market dominance, before rapidly dropping away to insignificance.
NB: It breaks my heart to say this. I've loved Bitcoin since 2012.
