MSTR in a retirement account definitely makes sense.

I’m not against MSTX/MSTU, I just think they are for very short-term trading and when a trend is clear (like a couple of weeks ago).

BTW - obviously I’m not a day trader or invest for a living but likely similar to you just enjoy the markets and have been learning daily for a long time. Investing has so many avenues it can be a lifetime of learning.
