I think it is funny that someone zapped me 1 sat. It cost me more to lower my thumb to the screen of my phone. I’m very fortunate and thankful to be able to give more than 1 sat at a time. I think the default is default Is 100. There are 17 Sats in 1 penny. So 100 Sats is about 6 pennies. I also notice, the more Sats I give them more I get back. I haven’t had to send Sats into SN in months. I think I only sent my own Sats in for the first few weeks and now I have a balance that I can’t seem to deplete.
