Make a large initial transaction into the wallet and then send at least half of it back out to another wallet. The initial transaction will establish a larger channel and sending some out will create plenty of inbound liquidity. The bull of the fees with Breez and Phoenix occur when they have to open new channels because of inadequate liquidity with your existing ones. So this will help minimize how often they do that.

This 👆 a lot of people think that 3000 sat fee minimum 10,000 sats or whatever is, is a regular thing.
But if you send a large enough transaction of the amount you'd likely keep before sending on chain you'll likely only need to do it once.
