Rotation Slippage
Rotation / Dual strategies only. 0% = ideal execution assumed.
How slippage works: Rotation strategies hold STRC, collect dividend (~15th), sell and buy SATA, collect dividend (~1st), then rotate back. Each sell-and-buy event incurs a spread cost. At 0.5%, two rotations/month = your share count shrinks by ~1% monthly, compounding over time.

Custom Strategy Builder
Build Your Own Strategy
Design a bespoke allocation across STRC, SATA, and direct Bitcoin. Then choose exactly how your income is reinvested — into STRC, SATA, BTC, or taken as cash. Run the projector above first to set parameters.
Capital Allocation
STRC 50%
Invested in STRC preferred stock
SATA 50%
Invested in SATA preferred stock
Direct BTC 0%
Auto: 100% − STRC% − SATA%
Remainder held as direct Bitcoin
Income Reinvestment Mode
Where to reinvest income (must total ≤ 100%; remainder → BTC)
→ Into STRC
→ Into SATA
→ Into BTC (auto)
= 100% − STRC% − SATA%
Split income across destinations (remainder → BTC)
→ Cash Out
→ Into STRC
→ Into SATA
→ Into BTC (auto)
= 100% − Cash% − STRC% − SATA%

Sharpe = (CAGR − 4.5% risk-free) ÷ annualised volatility. Strategy Sharpe estimates in the projector use historical volatility proxies: preferred stock ~8%, BTC ~75%, weighted by final BTC portfolio share. Historical performance does not guarantee future results.
