How to best store small amounts of BTC in self custody?

Hi,

I bought a small portion of BTC for a friend who has no exchange account and wonder what's the best optionfor her to store it. Cold storage device would not make sense (yet), as the value is not that high and I thought about creating her a hot wallet.

keeping it on my exchange could cause taxation issues, if my friend wants to sell at some point, as I would be the official "owner".

what do you recommend?
