In my opinion, it is good as long as you are able to secure the recovery seeds properly and safely. There is a lot of evidence that people in the past succeeded in doing this, whether intentionally or not, where the seeds of healing could be accessed again so that they were able to become billionaires today. When it comes to retirement investments, it is also a good choice to at least have someone who can look after your assets when needed. Not only as a retirement investment, Bitcoin is an inheritance for our children in the future by preparing everything that will later open up access to the inherited Bitcoin.
