Because debt repayment takes priority, MicroStrategy's Bitcoin strategy also recorded its worst bi-weekly performance: one week with no purchases, and the other week only buying 130 BTC. The main issue is the overly aggressive fundraising from the previous preferred stock issuance. Now, they have to pay large interest amounts to holders every year. So the money originally meant for buying BTC can only be used to repay debt. Fun fact: The money used for debt repayment also comes from selling stocks or fundraising.
