I think this is a healthy correction for a market that's currently accumulating a lot of scars, with this USDT exuberance in particular. Bitcoin for me is still an overpriced asset because it's main use at the moment, outside of speculation, is to trade against alt-coins in the hope of making more Bitcoin. What I see before me is that the space is becoming more and more of a sideshow with money flooding in to coins which are worthless. Many people in this space have grandiose visions of how they will be hailed in 2025 as one of the early adopters but I think I'll look back with some embarrassment about what is going on in front of our eyes.
There's a lot of hope/attention being pinned on the lightning network but with the inertia in getting wallets and exchanges to implement SegWit I don't see that turning around soon. Implementing changes like that on such a dynamic system which has to be live all the time is a bit like trying to tie your shoe laces while running at speed.
I think self-regulating decentralised exchanges will go some way to treating the problems in this sideshow that the space currently has but whether that will tackle adoption issues is hard to tell.
