Fiat currencies are being debased globally by central banks, creating false purchasing power that inflates asset prices. Bitcoin is a new and better form of money with a fixed supply and global demand. For most people, converting excess fiat into Bitcoin and holding it long-term (via dollar-cost averaging, even leveraging home equity) is the best way to preserve wealth because Bitcoin will appreciate faster than houses and other fiat-denominated assets, driven by increasing demand against a finite supply.
MicroStrategy's STRC is a preferred stock that pays 11.5% in dollars, making it a no-brainer for average fiat investors who have not yet seen the light of Bitcoin. It is an attractive yield instrument that he recommends without hesitation.
