+# Operation Saylor
+
+Operation Saylor is a financial investment with the goal of:
+
+- Earning BTC
+- Collaborating in the collapse of fiat
+- Keeping my wealth underground
+
+This repo contains documentation on the plan and the execution. A brief index
+of the contents:
+
+- `plan.md`: an overview of the general approach.
+- `register.xlsx`: a small spreadsheet to keep track of all transactions.
+- `simulation`: stuff to simulation the operation saylor itself according to
+  historical data. Was mainly used to make the decision of pulling the trigger,
+  but it would be interesting to compare in the future how things went against
+  these simulations.
+- `xpub`: the xpub of the cold wallet.

+# Operation Saylor plan
+
+The idea of Operation Saylor is to:
+
+- Borrow money from the bank through a personal loan.
+- Quickly DCA the loan into BTC.
+- Pay the loan back by slowly turning as-small-as-possible amounts of BTC into
+  fiat as-late-as-possible.
+- Hope that, by the time the loan is paid back in full, there is some BTC left.
+  And hopefully, with a decent economical value.
+
+## Loan conditions
+
+The loan I can get through my usual bank (Bankinter) comes with the following
+conditions:
+
+- Principal: 33.200€
+- 120 installments in 120 months
+- APR 5,99%, APY6,16%
+- Each installment would be of 368,42€
+- Early amortization penalty of 1%
+- No opening costs
+
+## Capital deployment and transacting
+
+The whole operation will be undercover, tax-wise. All buys and sells will
+happen P2P through bisq (or any better KYC-free service that appears in the
+future) and won't be reported to any tax office.
+
+To minimize the risk of entering in the very-worst-moment, the loan principal
+will be used to purchase BTC in equal fiat amounts during six months. Not all
+of it will be deployed: the equivalent to 3 months of installments will be left
+in fiat. Any time this small fiat amount goes below two installments, a small
+piece of BTC will be sold to have at least 3 installments in the account again.
+
+To be quiet and secretive, the purchases during the first six months will
+happen through four different bank accounts. That will spread the volume enough
+across different entities so that no single observe can realize the actual
+extent of the operation purchases.
+
+## BTC funds storage
+
+The BTC funds from the operation will be stored in two locations:
+
+- A small stash of (initially) 0.1 BTC will be kept in the bisq hot wallet for
+  convenience when turning BTC to fiat to pay installments.
+- All the rest of the BTC will be stored in a BTC cold wallet. The seed phrase
+  will be generated with a Coldcard MK3. Paper copies will be left in the usual
+  locations. A xpub will be used to set up a watch only wallet, and also kept
+  in this repository in case that wallet fails.
+
+## Accounting
+
+I will keep the accounting from Operation Saylor as separate as possible from
+my personal accounting. I want to track the performance of this Operation on
+its own, without blurring it because it gets mixed with my personal finances.
+Even so, there is an issue: the fiat I will be using during Operation Saylor
+needs to live in my own personal fiat accounts. If I don't record that fiat in
+my ledgers, I won't ever be able to properly reconcile my fiat balances without
+tremendous effort and a high chance of screwing up, with the awful consequences
+of the confusion that would come forth.
+
+To fix this, I will include the fiat amounts in my personal accounting in the
+following way: I will open sub-accounts for Operation Saylor in the four fiat 
+accounts I am planning on using. All the money related to the Operation will be
+recorded in these "virtual" accounts. This way, I will keep it separate from my
+personal balance and still be able to reconcile the total account balance with
+what will appear in my online banking systems. The origin of these funds will be
+a liability account, reflecting that this money doesn't really belong to "me",
+but rather to Operation Saylor.
+
+Regarding the BTC balance and all purchases and sales, I will run a separate
+spreadsheet to record those. That will enable a more flexible tracking and playing
+around with data than what gnucash would allow me to, and the operations are 
+going to be simple enough so that the serious ledger is not missed.
