Here's how the stars can align for LTC:
1) SegWit
2) Confidential Transactions
3) BTC forks and BU becomes the dominant chain
4) Coinbase adds Litecoin (not just GDAX)
1 & 2 alone are a $20 target for me.
Adding 3 is a $50+ target.
4 kind of just reinforces the Core chain dying and being replaced by LTC... core devs can start "fresh" on something that doesn't have the bad stigma of the BU fork, and is already technically better than Core: $100+ (bubble, not maintained)
One can dream right?

We've seen LTC do "this" before, so I also won't be surprised if I wake up tomorrow to $4.50 again, much like I woke up to $7 today.
The good news is, it only takes 75% compared to 95% in BTC, but why is it stuck at 22%? and what are the realistic prospects of this changing anytime soon?
Pools are being lazy, but the other reason could be that whales need time to accumulate positions. Once they have them, flip the switch f2pool...
