The first time I used strike to pay my mortgage I got super worried because it didn’t show up on the day it was due (on Strikes end) but the bank got the money. It just showed up on strike later.
Strike is useful to pay fiat bills, and stack sats. Just remember to decide how much you are willing to possibly lose and withdraw to your own wallet. There’s always the possibility that something like FTX could happen again. Whenever I accumulate a specific amount of sats, it auto-transfers some of it to my cold storage. I leave some on for bills.
Some people diss strike because you don’t hold your own keys but until every business accepts bitcoin and all income comes as bitcoin we’ll need some sort of middleman to navigate fiat-world.
