If you do have the money then going both coins would really be the best thing. I have known LTC isnt really moving on previous months or even years but now on the news that it might activate lightning network then its really possible for its price to rise up now and i do really strongly believe on that one and if i do really have the money i will put some funds into that coin and specially to bitcoin it wont really be left behind. Yet there are still other choices too which diversifying would be the best thing to do as of now.
