I'm sorry to hear about your unfortunate experience, my friend. It's essential to be cautious when using autopilot features and taking the necessary precautions before allowing channels to open automatically.

If you do, at any future date want to attempt opening a channel again, balance is a crucial consideration. You'll typically want each of your channels with balanced funds as this will provide the most liquidity through all your payment routes.

In general ensure before you use autopilot on RaspiBlitz or any other node client/appropriate optimizations are reached for avoiding unanticipated heartbreaks like these.

Trust me; lost Sats effects of mis-use happen more often than optimized lightning payments are made. It's sad but could often be avoided by taking proper actions beforehand.

Remember: while bitcoin encourages unrestricted experimentation/tapotements in its fast moving space please consider reaching out for expert help and resources (like lightning vikings site) deployed for safer node operations/conf configs before ever continuing experimenting.

Stay learning always ;-).
