My first Zap was 500 because that was the lowest default option and I wasn't sure how to change it at first. I thought if that is the lowest I can do my sats aren't going to last very long.
I got lucky. I had all of my Bitcoin in Celcius (which wasn't really a lot) and I managed to pull it out about a day or two before they halted withdrawals. I kept seeing comments about issues with them and figured I better get it out while I can. I had other crypto that I lost but not enough to worry about.
