Bitcoin as a savings technology

In his YT videos Joe Burnett (worth watching) said something that I had not considered before.

It was something along the lines of keeping most of your wealth in BTC indefinitely instead of a savings account, and only converting to fiat if you need to pay a bill or go on vacation etc.

Then he said something like:

In Dollar terms the cost of the coffee beans he buys have become 45% more expensive in the last 5 years.

In BTC terms they are 85% cheaper than 5 years ago.

Does anyone see BTC in this way?
