One time 3k to open channel. Channel stays open till you close it.. and it will give you both lightning network address or you can choose on chain transaction..
Discussion
Because from what I understood, each 25k satoshis deposited, you need to open a channel
You are right.. 🤔 I just did some test transactions and yes for lightning transaction. Over 25000 is another 3K sets. But if you do a regular online transaction they don't charge you anything. I'm waiting for the on chain transaction to confirm..
Now I got 3 channels open and it was 3k sats lol
1. Can send big amount over to make phoenix open a big channel (pay cost once)
2. Pay most of it out to cold storage
3. Channel remains open, use for wallet in/out
