Am I crazy for considering opting out of my pension and putting it in Bitcoin?

I’ve been listening to a lot of M Saylor recently.

Unless a pension fund is growing at least 7% a year, likely closer to 20% these days, anything I put in a pension is losing money. Right?

I have at least 30 years of pension contributions left to make and, as it stands, my pension projections are weak. Im in the UK and it looks like I’ll be able to retire at 68 if I’m lucky and get to budget for the rest of my life.

At least if I invest in Bitcoin it won’t devalue. Am I missing something? Even at a low rate of inflation my pension will devalue by like 90% in 30 years.
