My guess is that hedge fund money is accumulating and positioning for a drive to $10k/BTC once the ETFs are live.
You will see the log charts all over the media guaranteeing $10k per coin based on previous bubbles.
Retail investors will throw a few bucks into the ETFs and it will become a self-fulfilling prophecy.
Next leg up to $100k will be retail + institutional + sovereign wealth trying to jump on the train, say 2-3 years.
By then BTS will be mature, investors will have gotten a taste of crypto-riches and the moon rocket will launch.
5 years BTC could be $100k and BTS could be $100.
That's too good to be true
Historically, all financial bubbles didn't live for longer than a few years. Bitcoin doesn't have enough utility to justify such valuations, it's basically a ZX Spectrum computer in a growing PC market. If the price goes high enough, it will be easier for speculators to profit from shorting than from pumping it further. Actually, I do want BTC to go to ATH again, it would indeed spread the "taste of crypto-riches" and helped other crypto projects, including Bitshares. I just don't see it happening...
BTC has brand recognition, network effect and momentum.
You are absolutely correct on the utility aspect, but its good enough to move value around the globe quickly, cheaply and reliably.
DPOS/BTS is superior in every way, but PoW will die a slow death.
