How do you stack your sats?

At the moment I use:

1️⃣ Robosats to buy

2️⃣ Phoenix to receive

3️⃣ Phoenix to swap to onchain

I used to directly receive it onchain but this seems more cost-effective.

I have to only open channels once, so open fee applies once. Then I only have small robosats fee, and mining fee. No swap fee on robosats.
