We are a young family, keep a significant fiat reserve for bills/immediate expenses. I don't want to have to sell SATS to repair a car or replace a water heater. I could really use some coaching on how to swing it for 2 reasons.

1 how to deal with taxes (I do see strike has a system to help)

2 (most importantly) what happens when BTC goes down and now I'm selling BTC at a loss to pay for cars/water heater
