60/20/20 sounds like a lot depending on how much is in your vault/multisig.
For me it's more like 5 times less than the more secure one. So assuming my total stack is 124, I would go for 100/20/4.
I don't have a set ratio or amount. I keep what I think I might spend soonish on Ln the rest on-chain. average ratio over time for me works out to about 1:50.
I'd say in the current market just to keep a few million sats. On chain transactions are super cheap (110sats).
But I might start putting more into lightning over the next year before the halvening. It would be a good idea to prepare a little for another bull run & congested mempool.
According to mempool.space to get into the next block, this is posted at 9:39pm EST btw, you need to pay at least 3 sat/byte. That's about 10 cents or 426 sats
Yeah, but 1sat/byte are getting through in a fee hours. Depends if you need it sooner OR if an exchange like binance consolidate dumps on the mempool. Then you might need to pay more
Depends how much you have, rich people need smaller amounts of their wealth readily available for their life's expenses. if you have 10 million dollars of bitcoin, having more than $1,000 on LN is excessive IMO, and so your ratio would be 99.99 % on, .01% off chain
But in general...
Keeping it off chain is best, and the colder the better
So most in a onchain cold wallet you access once a year: 75%
Then a "warm" onchain wallet you access once a month 20%
Then a hot onchain wallet you access once a week 4% this is where you switch it to your...
Every day offchain wallet 1%
It's now about 1 dollar or less to move it off chain, I guess if that doubles or triples, doing that once a month could save some sats.
