"I suggest custodian wallets for amounts like 0.00069376 a year." Can I tell you more about this? what did you mean?
For example, my clients will transfer me let's say 60 rubles a month in total, this is 0.00005788 for a year this is 0.00069376
Because, you'll have to pay a fee that might take a portion of it to spend that balance because you'll end up with lots of very small
inputs.
Transaction fee will be based from the fee rate (
which you'll set in the wallet) and the transaction's virtual size which will get higher if it has a lot of
inputs.
1sat/B is still good enough to consolidate them though.
Custodial wallets will just send from their hot wallet when you want to withdraw (
minus their fee which can be cheaper for low-priority).
Personally, I'll use a custodial wallet for that amount.
LN is a very good choice however won't let you receive 'savings' from your 'clients' unless you have enough inbound capacity.
And you don't have enough funds to open a channel of 0.002 BTC then use submarine swap or spend some satoshi.
You need to find a way to increase your inbound capacity like mentioned in the previous sentence.
I mean that now I transfer over the real network first from a multisig wallet to two already existing LN. In the test network, how do I do that?
I don't get it.
But everything you can do with mainnet, you can do the same with testnet.
I will always have sufficient incoming capacity, since all clients will open channels to me with sufficient local capacity, for me it will be just incoming if there is no routing of the passing nodes, which I am going to do - do not use routing nodes between us
