My thoughts exactly. I think we'll see a bubble soon and the bubble will pop, shaking off all the dead leaves from the tree.
As far as alts decoupling from BTC, I think you're wrong. More things will be valued relative Bitcoin, as time goes by... Not the other way around...
I agree that blockchain has a real future, but it’s not in the 900 Alts currently saturating the market. These are pure speculation plays on tiny changes to code that are never going to be viable products in their own right. Most have no real use case and offer nothing. Consolidation is in the cards but all the while prices are so high,
