The yield that MSTR could generate by lending a portion of its bitcoin holdings could offset the annual interest on its debt, and if the company were to become comfortable lending larger amounts, then it could use the associated yield as another means of adding to its holdings, one that would not involve any qualms about leverage or dilution.
Now, do you understand why @saylor wants to get yield on his stack?
IF he can do this without getting ruggged, he can basically freeroll stack bitcoin.
