Ok, thanks for that info. I think it would be ok to leave your minimum at 100 sats, but at least make it so that's clearly the policy. Like if my balance is 24, I shouldn't be able to click the [WITHDRAW] button, or if/when I do, it should give an error message about the minimum withdrawal amount.

I deposited some more sats, this time by sending to my satoshi@lnroulette.space lightning address. That worked perfectly.

I played more with my new 50 sats balance. I won. New balance = 100. Tried [WITHDRAW]. Used Alby firefox extension that popped up when clicking on the LNURL QRcode. It worked. Received 94 sats. It's understandable that 6 sats went to the transaction fees, but that's only because I've done enough lightning transactions to understand it. There should be some sort of notification message indicating so, otherwise you'll end up with newbies complaining about doing 100 sats withdrawals and only receiving 94.

All in all, it's a great start to a new site. Keep working at improving it. It would be nice if the code were open-source. I don't think it is. Is it?
