First, I don't think you understand what Bitcoin is for.

Second, an example:

Building on existing IRS rules that limit interest deductibility for investment-related debt (such as under Section 163(j) of the Internal Revenue Code, which caps business interest deductions at 30% of adjusted taxable income), the government could introduce targeted legislation classifying borrowings for cryptocurrency purchases as "speculative" or "non-business" expenses. This would fully disallow interest deductions for debt-financed Bitcoin treasuries, like those employed by MicroStrategy, where convertible notes and loans fund ongoing acquisitions.

Justification could stem from treating crypto as non-income-producing assets until sold, similar to how personal investment interest is limited to net investment income. For companies, this would inflate taxable income by the full interest amount (potentially billions annually for high-debt entities) forcing them to pay taxes at corporate rates (currently 21%, but could rise under proposed hikes) without offsets. Individuals involved, such as executives with performance-tied compensation, might face imputed income taxes if corporate shortfalls lead to restructurings or personal guarantees.

This remains legal as an extension of existing deduction limits, enforceable via audits and penalties for misclassification, and could be enacted through budget reconciliation to avoid bipartisan hurdles.
