Halving seems to be already priced in heavily. The pump last month was on the halving hype. I think LTC will slip further...
It has dipped again and I thought that the last price would be above $90 but now it's starting go decrease. You are right that it will slip further and it's likely that it will just stop after bitcoin stops slipping.
If the halving was going to have any positive effect on the price of Litecoin, you would have known by now, the halving is just three weeks to go and the value of Litecoin has still not made any significant move, which means people are not paying much attention again to Litecoin unlike before.
Not that really, I think everyone is following the Litecoin halving but it's just the market that has been slipping down due to the king's movement. And Litecoin is not exempted with this move.
