I live only using BTC.
So my answer will be: whenever I need to pay a small amount (bellow 1M sats) I will use LN. Larger amounts - onchain or using MPP or split payments on LN. Is not about that LN is not capable to do a larger payment, it is, but nowadays are few routing nodes that will have a decent fee and enough liquidity and good peers to forward my payment.
So I will strongly suggest to new LN users to not try larger amounts, your payment will fail or will have a higher fee than onchain. We still have greedy LN operators.
I know this is not a polite question…
But do you live only with bitcoin because you get paid with bitcoin on the work you do or you are able to live with the bitcoin you purchased years ago ?
I've been recommending it to my new stacker friends who I want to get off exchanges, when they see they can buy $1 worth of bitcoin they feel its de-risked and then I say get to your 1 million sats and then lock it in your "vauld" and try and gamify it for them, works for some
