a year from now (about the time LTC having takes place) a lot of things may have already changed and the price may be literary anywhere.
for example we may see a big drop in LTC price as other better altcoins come up and change the top 5 places and replace all of them and push these coins down.
or we can finally see LTC lightning network pick up alongside bitcoin lightning network and we see a lot of adoption for bitcoin and consequently for litecoin also leading to its price rise. in which case we may even see above $2000 prices.
