My wife came up with a potential strategy (UK) for MSTR.

Put spare money into an ISA in MSTR. Any gains under £20k per year are cap gains free. If you get some good gains. Just before the end of the tax year. Take profits and put into a SIPP (personal pension) in MSTR. This would help off set your personal tax owed as pension contribitions are tax efficient. If over the year MSTR has done well (we think so) then you can use the tax free gains to reduce your income tax. If this is allowed then my wife is one clever lady. Someone tell me if this can be done. #cheatcode 🫡
