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.
$98.5M in the last 24h. LTC Market cap is currently $417M
$98.5M / $417M = 23.6%
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.
