This seems to have nothing to do with "Development & Technical Discussion".
But a "crash"?
It is still about 30,000-100,000 times higher than it was in 2010, and 10,000 times higher than early 2011. And ~10 times higher than 52 weeks ago, so it hardly seems like a crash.
Give it some time - when ETFs are available, when lightning is active etc. - who knows where it will go, but micro-payments, ETFs and all the other uses that the Bitcoin blockchain can support with SegWit and script versioning are huge benefits.
If the fiat price of bitcoin in 2018 “crashes” like it did in 2017, anyone who is long bitcoin will be happy.
