That's a fair concern, but I'm actually more concerned about fiat than Bitcoin, mainly so with how the demand for a tiny dot such as Bitcoin can only increase in the long run, thus the purchasing power of those holding it.

I think an additional demand factor for Bitcoin is the fact that physical cash is being banished slowly but surely. Bitcoin is the only digital asset that you can hold permissionlessly. In the same way, I strongly believe it will increase the demand for physical Gold because there will always be people valuing something they can actually hold.

I'm a fan of anything that is durable and portable to be used as a wallet. I have been experimenting with steel plates that I engrave private keys in manually, and I actually like idea behind it. It's far more durable than a paper wallet, plus it can resist temperatures of ~1000 degrees celcius. Inside a safe, it's destined to last.

Steel plates cost a few bucks, and an engraving pen costs somewhere between $25-$50 brand new. Great value for money I would say.
