I'm always a little worried when I gift on chain btc. What if the recipient doesn't take it seriously and loses the keys? Also if it's too small, it could be dust if fees go up a lot (the mempool will never clear...)

Ecash is a great idea, if you lose it, at least the sats aren't burned. (Haters will say this is my implicit admitted ssion that ecash is custodial, but it's not.)
