Other options, if you are wanting listed companies that actually hold Sats on their balance sheets, include:
MicroStrategy (MSTR)
Tesla (TSLA)
Galaxy Digital Holdings (BRPHF)
Voyager Digital (VYGVF)
Square (SQ)
Marathon Digital (MARA)
Coinbase (COIN)
Mercado Libre (MELI)
Twitter (TWTR)
PayPay (PYPL)
Actually many more once I start listing, and many more also in Asia and emerging markets too where I primarily focus my time,
And of course many more companies have exposure to BTC as part of their business activities but may not classify it as a treasury asset.
So to a point that a person posted earlier, yes, we all will get greater exposure over time, as global BTC networking and integration etc permeates more and more of our global monetary system. The decision to hold directly is really simply a matter of concentration. Eg, do you want greater exposure that the average person (which would give you huge upside if this trend does continue), or, do you simply stay exposed to the economy generally via a broad mix of stocks via an ETF (in which case you will participate in the adoption), but not greater than the average participant.
A massive game changer will be direct ETF listed in the US. This will essentially open the gates to any fund, investment advisor./manager, mom and pop investor, private fund, HNW etc who so far have not felt comfortable with existing options. If you believe that almost all would likely, over time, allocate just a little to such an ETF, and if you believe that such an ETF is inevitable, then you would definitely want to get in now, prior to this occurring. So again, what this comes down to, is your confidence (or desire for exposure) to future societal change (for which they cannot be absolute certainty, but only estimates and predictions of likelihoods of occurrence).
