I cannot think
Correct. You can't think.
Watch and learn.
Next time you'll read what I wrote.
I already debunked this nonsense thread of yours.
But all you said were copy and pasting all your
theories and arguments of what you think. Those cannot be proven until it is done in practice. How is that debunking the question if Segwit is really necessary?
The point of the question is if it is necessary now with the current usage of LTC. It will be an improvement I am sure. But is it necessary from the point of view of a user?
You first have to ask yourself, how is it being used now? Why do we need Segwit now to open the roads to a Lightning Network?
Litecoin has one and only one chance to ever get SegWit activated now while LTC is extremely undervalued (because this means miners can form a 75% consensus on rising the price, which won't be otherwise be possible due to the
crab bucket game theory that John Nash designed into Satoshi's PoW). That window of opportunity will close and due the crab bucket mentality that Satoshi designed into PoW and never be possible again in the future.
Without off chain LN, there is no other way to scale Satoshi's PoW. I've refuted all the other technological BS such as larger blocks and Xthin.
Bitcoin will NEVER get scaling.
Litecoin MUST get scaling NOW. And it will. And it will receive all the transaction rate scaling that Bitcoin will NEVER be able to do.
Please don't make me explain this again.
The volume on LTC is building. LTC has far too high of volume lately to stay so undervalued. The pressure is building. Also, fiat is coming into LTC via Coinbase, so that in my mind is enough to push LTC's price up regardless of SegWit activation.
The volume is indeed insanely high.

I can't see LTC not going up again

when price is changing volume goes up too, it doesn't matter if it is changing for the better or for worse (down or up) and it only shows people who are making trades to take advantage of the changing price in short term aka day trading. and you can't say it is positive. and in this case the high volume shows a massive dump in the past 24 hours.
what is positive and shows good signs is when price is stable or with little change but the volume is high which shows accumulation with smart money coming in without anybody noticing.
i am not saying litecoin can not go up again, i am saying your conclusion is wrong.
The volume is extremely high but
it is not a panic waterfall collapse. That to me is very bullish. It indicates to me the smart money is trying enter at the lowest price they can before the next blast off.
Nearly all the altcoins are down because the market is confused and thinks that Blockstream has defeated Jihan Wu's BU, but I expect BTC is topping out at $1200 (range bound as I predicted many days ago) once the market realizes that this BS about SegWit signaling on Bitcoin gaining momentum is nonsense. Bitcoin will never get scaling. The market will digest this, Bitcoin will stumble and Litecoin will rocket up.
The market is stupid because Bitcoin will actually benefit from scaling on Litecoin, but the market has to go through its gyrations. In any case, my thesis is Bitcoin remains range bound until Litecoin catches up, because the charge says "It Is Just Time" and because Bitcoin can't move up until there will be scaling in the Satoshi's PoW ecosystem. Litecoin will get it, Bitcoin won't, but that it is a good thing for Bitcoin. Market doesn't realize any of this yet, but the smart money does.
