I sold all the Vanguard fund shares in my brokerage account & used some of the proceeds to stack 15 shares of ARKB Spot Bitcoin ETF.

15 shares is the equivalent of .015 Bitcoin or 1,500,000 sats

I particularly like ARKB as an ETF because one share is equivalent to .001 BTC

So you know how exactly much BTC you “own” inside the ETF wrapper.
