I hold some MSTR in my pension fund. In the UK Bitcoin derivatives are banned, so the best you can get is Bitcoin-adjacent stocks.
I once held mining stocks too (Hive, Riot, Marathon, and... Core Scientific lmao).
Miners are less desirable to me as they are more dependent on non-Bitcoin things: Energy prices, ASIC production, US mining regulation, etc. Whereas MSTR just have to sit on a fat stack of corn and not lose it.
