I've been going at it with a hundred cuckbucks charging 2/2.5/3. I'm making 10k sats per trade. Strike sends lightning transactions with fiat, i've been sending the profits via lighting to my node. 

cool, what kind of % premium do you typically charge? 

it looks like things are settling around 2-3% for most BTC <> fiat trades across the exchange

Hey its crazy over there, been playing with it for a couple of days, prolly earned 40k sats so far. Jam looks good too, waiting to see how much it pays out. Shoutout to start9
