RabbitSuit Fund
Ein Bitcoin-Fonds, den wir mit eigenem Geld betreiben und offen berichten. Wir tun das für unsere eigene Disziplin und für alle, die es interessiert; nichts davon ist Anlageberatung.
Das Ziel: Renditen wie beim Halten von Bitcoin, mit deutlich kleineren Rückschlägen auf dem Weg. Wir messen das an Sharpe und MAR, den risikobereinigten Kennzahlen. Warum Bitcoin →
Eine Regel legt jeden Tag die Mischung fest: Sie entscheidet, wie viel des Fonds in Bitcoin liegt, irgendwo zwischen 0 % und 100 %. Steht der Regler auf 0,65, liegen 65 % des Fonds in Bitcoin. Der Rest wird in einem anderen Asset geparkt.
Dieses andere Asset ist eines von Cash (Geldmarkt), Weltaktien, Gold, der Nasdaq-100 oder lange US-Staatsanleihen, zu jedem Monatsende per Regel neu gewählt. Ein Wechsel verändert den Bitcoin-Anteil nie.
Obendrauf kauft eine kleine Optionsposition Konvexität, wenn unsere Strategie es für lohnend hält. Sie kann nur verlieren, was sie gekostet hat, und verändert nie den Bitcoin-Anteil.

An options position that expires on the same day a new one would be bought still counts as money tied up when the fund checks whether the parked share can pay for the new one. Its proceeds are not used to pay for a purchase on the same day, because in the account the fund uses they are not reliably available that soon. The practical effect is that, when Bitcoin already takes up most of the fund, a new options purchase is skipped a little more often. In the historical record this skips three purchases in early 2023 and lowers the simulated return with options slightly; the figures without options do not change. The rule for when to buy, the sizes and the cap are as they were. It moves no position today and changes nothing the fund holds.
Reporting change; no rule changes. Two things. First, the fund now publishes two reference dials beside the one it follows: the dial as it would read under the rule in force before the last change, and the dial with only the four-year-average exception and no read-ahead. They are yardsticks: nothing is bought or sold on them. The read-ahead will be judged against the second one, the simpler rule it has to beat, and the yearly review reports both. Second, the wording. The read-ahead is a momentum adjustment on the fund's liquidity reading, chosen because it improved the historical record. The observation that Bitcoin tends to follow liquidity with a lag of a few months is what prompted it; the adjustment is not calculated from that lag, and earlier wording that suggested so has been corrected. Every rule, band, cap and figure the fund runs on is exactly as it was and nothing trades differently.
Two bounded changes to how the dial reads liquidity. First, when global liquidity has improved over the last three months, part of that improvement is read ahead. This is a momentum adjustment chosen from the historical record; the observation that Bitcoin tends to follow liquidity with a lag of a few months is what prompted it, not a formula it follows from. A deterioration is read as before, so the dial is never below what the old rule would say. Second, while Bitcoin's price closes below its four-year average, the liquidity haircut is not applied: at those levels the record shows the haircut costs the recovery more than it saves, and it comes back the day price closes above the average. Nothing else moves: the valuation and rotation factors, the executed dial's memory, the floor, the bands, the parking rule, the options position and every override are as they were. The rule was re-backtested over the full history before adoption and judged on return per unit of drawdown; it improves the record on every window and passes the after-tax check. It is not free of cost: in the past it would have held a material Bitcoin position through the November 2022 exchange collapse, which cost about twelve percent of the fund's value in a fortnight before the 2023 recovery more than repaid it. It makes no trade today: at the current close the new and old readings are the same number.
The fund now accounts for when Federal Reserve balance-sheet information becomes available. Historical simulations also use earlier information for the valuation reference and include ETF distributions consistently. Actual past decisions remain the fund's record. The allocation effect was checked against the production state; future rebalances follow the existing execution rules.
