Low fees are the only advantage of LTC but even Bitcoin (in these days) you can broadcast a transaction for 15 sat/vByte and get confirmation in less than 20 min.
But $1.5 plus $1.5 and multiplied by 50 weeks a year starts pending in anyone's wallet.
I'm saying twice 1.5$ because if you send some coins the guys receiving them has also to pay to use them as it's not a bank deposit, then if you have multiple outputs and so on, if your CEX is a shitty one that charges more for BTC than LTC or Doge (cough , Binance) you look back at a year of expenses and you realize even 2$ for a tx is too much for random weekly usage.
And I think daily or weekly usage is dead on Bitcoin, we have sky-high prices compared to 3 months ago, fees have flattened despite half of the block space being used by ordinals and consolidation, I think that most deals have shifted to stablecoins as not only fees but volatility has also become a pain in the ass
Anyhow, finally, the mempool is not during above 1.30sat/vb for the default 300MB settings, two more weekends and nothing out of the ordinary and we might see 1sat/vb not being rejected by default nodes.
