One side believes segwit will work, the other side believes it will make very little difference.
You're kidding me... you really think segwit won't "work" the way it was intended? It's been deployed for over a year on testnet (unlike segwit2x) and has been deployed on litecoin. Sure litecoin has precious little use for it but it's still in use and does exactly what it's supposed to. Or are you saying that exchanges and users simply won't use segwit transactions? Exchanges will jump ASAP for the benefits it provides and they do the bulk of the transactions (except during mempool spamming and then it's 'someone').
Uhhhm but since Litecoin activated Segwit, why do less than 1% of Litecoin transactions use the Segwit transaction format? And only a few Lightning transactions have even been processed?
Litecoin didn't even need Segwit (blocks were nowhere near full, and Litecoin was marginally a shitcoin), it was an excuse to pump the Litecoin price and hype up the benefits of Segwit. Which have yet to appear.
More dumping on today's news. People are starting to murmur about August 1...
