Gold -> Good, and Bitcoin is like Gold in many aspects. While it doesn't have Gold's history yet, it has a few other qualities like easy transferrability and divisibility.

In general, Bitcoin (like Gold) is a great asset to park some fraction of your wealth as a hedge against geopolitical risks.
If I put money in my savings account, I can use it tomorrow. If you put money in your BTC savings account a year ago, your BTC is worth less than money under a mattress (or in a modest yield savings account).
You may want to invest in BTC, and that's absolutely fine! But it's not a savings account.
