The fact that litecoin is moving do the opposite direction. The first picture is clearly telling us how litecoin is always weakning against bitcoin. It has 350x ratio against bitcoin, which is far worsen than last years.
To be a great investment like bitcoin, it has to follow bitcoin's movement. So let's focus on the 2nd picture, which is showing how litecoin's annual return is just too far away compared with bitcoin.
I'm still questioning why people are still calling litecoin as a silver when the statistics and data are saying the opposite. For me, it's not an asset that is worth to hold.
There's nothing you can expect from a coin that has its creator dumped its own coin.
Litecoin is called "Silver to Bitcoin's Gold" because of its reliability. Limited supply is another fact. But the main one is reliability. Especially when compared to other cryptocurrencies. Rival chains are newer, and widely unproven. Consider how Solana has been a victim of constant network outages in the past. Litecoin has been steadily running since day one (AFAIK). Not only it's reliable, but it's also fast and cheap to use.
If you want the added scarcity with the security and reliability of Bitcoin, Litecoin would be your only answer. Not Solana, not BNB, nor TRON. Ethereum comes close, but it's now more centralized than ever with the switch to PoS. These are strong reasons for anyone to invest into LTC. It's up to you to decide whenever it's a good investment or not. Just keep "hodling".
