MSTR > ETF IMO.
If you have to do it because IRA, 401K etc. Otherwise buying BTC is always best.
ETF’s have outflows. MSTR has inflows only & a long term HODL strategy driven by Saylor.
Discussion
That inflows/outflows is a good point.
I prefer to just buy BTC, but I like to hold a bit in cash, in case shit happens. The TFSA gives me the advantage of not having to pay capitals gains if I sell, so I might as well use it for that purpose.
If the TFSA option wasn't there, I'd just hold BTC on its own.
Wealthy people love to avoid taxes. MSTR allows them to borrow as well against the stock to avoid tax. Huge.
