Yeah, a portion of my retirement funds. At such a stage you can't afford to be reckless, despite the trust btc has been able to achieve over the years there is still some level of risk,
If you are retired it means there is no other steady way to generate monthly income except you are able to invest your retirement fund wisely so you don't fall flat on your ass being careless.
So yeah, a small portion will be in btc and the rest will be in other investments that are less risky.
