If Blix works like Phoenix, what you want is to send as much as you can afford to open as large a channel as possible.

Let’s say you send 150k sats, Blix will open a 150k sats (plus an extra bump courtesy of Blix).

Now you need to take into account the concepts of inbound and outbound liquidity.

The channel you just opened will have 150k sats of outbound liquidity, meaning that’s the max amount you can spend.

But it’ll have only few thousand sats of inbound liquidity (remember the extra bump I mentioned), meaning you will able to receive only a few thousand sats.

What you’ll need to do is send, let’s say, 75k sats back to WoS.

Now your channel will have 75k of inbound liquidity and +75k of outbound liquidity.
