Stocks -> can be seized by governments where the exchanges or actual companies are based.

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.

Other assets -> Like? ForEx is at the mercy of issuing government (just ask Russia who lost ~300B$). Land can be seized if it's outside one's jurisdiction.

In general, Bitcoin (like Gold) is a great asset to park some fraction of your wealth as a hedge against geopolitical risks.

Bitcoin is not like gold in one important aspect that chiefly matters for a long-term store of value: it's much more volatile.

It's difficult to buy stocks if you don't even have a bank account. Why wouldn't Bitcoin be a "savings account"? I use it as a savings account, it's really great. I put money that I don't need today there so I can have the same or higher buying power in the long term, regardless of inflation.

BTC is an asset that moves around a lot.

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.
