I'd go with Litecoin. I have more experience with using it compared to Dogecoin and I've rarely touched meme coins before. It doesn't help that as you've said, it's supply expans infinitely. I also don't really like how the market went up all of a sudden beforehand all because of Elon and his shenanigans, probably the number one reason why I stayed away from it like a plague. Seeing as the case has died down though I might check it out at some point later.
That's certainly true, mate. Dogecoin's success is concentrated in Elon Musk himself. Almost everyone follows the man's advise when investing into DOGE. Talk about "decentralization". On the other hand, Litecoin creator Charlie Lee decided to step down from the project to make it more decentralized. There's no one to follow, other than the community itself.
We could say Litecoin's price is driven by utility instead of hype (speculation). The cryptocurrency (LTC) is often used to test new features before they're integrated into the main Bitcoin blockchain. With a limited supply of only 84m units, Litecoin has a high chance of becoming "Silver to Bitcoin's Gold" in the future. It's very undervalued to say the least. Hopefully, people will notice its true benefits resulting in a massive pump in market prices. Who knows how far will LTC go?
