Well, as mentioned it's my first Lightning-steps, so I'm still kindof experimenting.
Currently my channel sizes are 1-5million sats, so not that big,
some huge nodes, like deezy.io, Kraken, Boltz, bfx, nicehash,
but also smaller ones, some I opened through
LN+ swaps.
My best channels so far are Blocktank (cheapest provider of inbound liquidity I found) and Kraken,
with Kraken being the easiest and by far cheapest to rebalance (zero fee if you have Kraken-account), which is a nice bonus.
Next channels are probably going to be a bit bigger, like 10-25million, with a couple of smaller LN+swaps here and there to support newbies like myself.
For sure going to open a bigger one to getalby (again for ease of rebalancing), maybe Wallet of Satoshi too, but I don't use their app
and I definetely need a bigger Kraken channel.
The "hardest" part is getting inbound liquidity.
I can of course do swaps, "Loop" out, or simply buy some, but it's all quite expensive and I'm not getting much in return due to my relatively low fee-settings (zero base fee and ~100-500ppm).
Guess I'll never make any profit off it, but that's not what I'm looking for anyway, I just don't want to spend more than necessary.
