-snip- Dogecoin I would not give. Bitcoin would be better. But between BTC and Hardware Wallet, I would prefer HW, because it will be a physical, material gift, and not something abstract and not tangible, like crypto currencies. I'm trying to take into account your uncle's age, and therefore the habits of the older generation, for whom tangible gifts may be the best option.
Bitcoin is certainly the best choice, but why should the OP give DOGE, doesn't he have other options besides DOGE?
I also agree about the hardware wallet gift being an option for a gift, because the prize requires a physical gift and a hardware wallet is a choice. The hardware wallet can also be filled with bitcoin assets, quite easy and of course it will be meaningful. Old age will not be a problem as long as you still want to know new things or new technology.
Regarding hardware wallets, maybe Trezor, Ledger, and Safepal, because I use all three wallets.
