In my scenario, the price of Litecoin can increase by more than 10% in an hour.
Maybe it happen, if bitcoin doesn't dump. I don't think if halving will up ltc price if bitcoin unstable.
Many people have a positive opinion towards the LTC halving but we have to wait and see every coin price is going down along with the recovery of Bitcoin and dumping the price of Bitcoin, so now we are in complete fluctuation situation which there is no guarantee whether the prices will increase or decrease.
