On-chain gifts may be hard to move if not of significant size. If it was me I think a Liquid seed carved in steel for a small amount would be good, or a regular Bitcoin seed carved in steel (I'd just set either up on a Jade). You can gift them just the metal seed with the amount & instructions to recover it via the free default Liquid/bitcoin software they can download & run on any computer, or you can gift it with a Jade too which they can restore & setup for themselves. And just tell them to treat it like cash & keep everything in a safe.
