I always pay with Bitcoin when possible, unless it's onchain only for small amount or if the merchant use a third party service with crazy high fee or abusive exchange rate.

For example I bought all my Steam games with Bitcoin when it was accepted on Steam (with zero conf on-chain 🤩) and I always paid my Protonmail subscription in bitcoins. Also I go to a food truck accepting Bitcoin over Lightning, 2-3 times per week.

When I can I buy back the sats shortly after or I stack in advance in the purpose of these pucrchases, but I must admit that I didn'nt in the beggining, like on Steam, which I should better not check how much sats (whole bitcoins!) I spend on these games at the time.
