You do realize that growing your inbound requires many on chain fees as well right?
UTXOs of less than 10 million sats will eventually be economically inconvenient to move on chain in the future.
UTXOs of less than 1 million sats are already becoming a bit expensive to move with the current fee environment.
I recommend stacking in a self custody lightning wallet like nostr:npub148qm45zettnf6ekgkatnyfadunxwjpu8sy88mjdsgwc5f202d93qmejra7 until you have a large balance. Then you can splice out to your cold storage address creating a large UTXO.
Watch how cheap and easy it can be to stack small buys 👇👀

You don't pay a miner fee when you withdraw from strike to Phoenix. Custodial lightning services handle channel management for you. If you pay attention to that video, it cost me 9 sats to make that transaction. You'll pay a single miner fee when you splice out to cold storage.
Buy 100000 sats on strike. send to Phoenix. Pay a fee for initial channel open through the LSP. Assume its batched for a lower fee.
Dont spend any
Tomorrow, DCA again, send to Phoenix. Phoenix may have opened with more liqudity on their side, so no fee.
Repeat every day for a month. At some point, all that liquidity moves to your side, and either another channel needs opened, or a splice. Either way, theres another fee.
Check your fee schedule and channel liqudity. Manage appropriately based on circumstances.
