## Abstract

A digital currency account stabilization system for maintaining valuation of a digital currency account balance against a reference currency. The digital currency account balance is maintained in a currency account and has an initial value. Hedging positions are opened to maintain the valuation of the currency account at the initial value. When the valuation of the digital currency fluctuates, digital currency is added or deducted from the currency account to maintain the initial value.

## Claims

### Claim 1

A method of maintaining a digital currency account, for stabilizing the value in a digital currency account with respect to a reference currency, the digital currency account having an account balance of digital currency, and simultaneously facilitating the use of the digital currency by an owner of digital currency account, comprising the steps of:
a) creating a digital currency account, where the digital currency account is maintained using a digital currency system configured as a network comprising a plurality of decentralized computing devices, wherein the digital currency system has a plurality of digital currency units implemented using a block chain transaction ledger stored on the network of decentralized computing devices, wherein the block chain transaction ledger records all transactions using the digital currency;
b) establishing an initial value of the digital currency account balance in the digital currency account with respect to the reference currency;
c) determining a gain or loss in value of the digital currency from the initial value;
d) adjusting the digital currency account balance by performing one of adding digital currency when a loss in value is determined and deducting digital currency when a gain in value is determined;
e) making an account transaction initiated by the owner which changes the digital currency account balance; and
f) repeating steps b through d.

### Claim 2 (depends on 1)

The method of maintaining a digital currency account as recited in claim 1, wherein the step of creating a digital currency account is followed by the step of creating a hedging position according to the digital currency balance.

### Claim 3 (depends on 2)

The method of maintaining a digital currency account as recited in claim 2, wherein the step of determining a gain or loss in value of the digital currency is followed by the steps of:
i) changing the account balance in the digital currency account by performing an account transaction, wherein the account transaction is transmitted to the digital currency system and recorded to the block chain transaction ledger by the network of decentralized computing devices; and
ii) adjusting the hedging position in response to the change in account balance in the digital currency account.

### Claim 4 (depends on 3)

The method of maintaining a digital currency account as recited in claim 3, wherein the step of adjusting the hedging position further comprises:
i) communicating the account balance change to an exchange; and
ii) one of: opening, closing, and partially closing at least one item selected from the group consisting of futures contracts, forward contracts, swaps, and derivatives.

### Claim 5 (depends on 3)

The method of maintaining a digital currency account as recited in claim 3, further using a stabilizing account, and wherein the step of adjusting the digital currency account balance is performed by transferring digital currency between the stabilizing account and the currency account.

### Claim 6 (depends on 5)

The method of maintaining a digital currency account as recited in claim 5, wherein the steps of creating the hedging position and adjusting the hedging position are performed by the stabilizing account.

### Claim 7 (depends on 1)

The method of maintaining a digital currency account as recited in claim 1, further using a stabilizing account, and wherein the step of adjusting the digital currency account balance is performed by transferring digital currency between the stabilizing account and the currency account.

### Claim 8 (depends on 7)

The method of maintaining a digital currency account method as recited in claim 7, wherein the step of creating a digital currency account is followed by the step of creating a hedging position by the stabilizing account according to the digital currency balance.

### Claim 9 (depends on 8)

The method of maintaining a digital currency account as recited in claim 8, wherein the step of determining a gain or loss in value of the digital currency is followed by the steps of:
i) changing the account balance in the digital currency account by performing an account transaction, wherein the account transaction is transmitted to the digital currency system and recorded to the block chain transaction ledger by the network of decentralized computing devices; and
ii) adjusting the hedging position by the stabilizing account in response to the change in account balance in the digital currency account.

### Claim 10

A digital currency account stabilization method, for stabilizing valuation of currency accounts, each having an account balance of digital currency, using a stabilizing account, comprising the steps of:
a) linking to a currency account having an account balance, where the digital currency account is maintained using a digital currency system configured as a network comprising a plurality of decentralized computing devices, wherein the digital currency system has a plurality of digital currency units implemented using a block chain transaction ledger stored on the network of decentralized computing devices, wherein the block chain transaction ledger records all transactions using the digital currency;
b) establishing an initial value of the currency account balance in the digital currency;
c) monitoring the valuation of said currency account according to the initial value;
d) transferring digital currency between the stabilizing account and the currency account to maintain the initial value of the currency account when monitoring of the currency account show that the valuation has increased or decreased;
e) making an account transaction initiated by the owner which changes the digital currency account balance; and
f) repeating steps b through d.

### Claim 11 (depends on 10)

The digital currency account stabilization method as recited in claim 10, wherein the step of transferring digital currency further comprises adding digital currency to the currency account when the valuation of the currency account has decreased and deducting digital currency from the currency account when the valuation of the currency account has increased.

### Claim 12 (depends on 11)

The digital currency account stabilization method as recited in claim 11, wherein the step of linking to a currency account is followed by the step of opening a hedging position according to the account balance of the currency account.

### Claim 13 (depends on 12)

The digital currency account stabilization method as recited in claim 12, wherein the step of monitoring the account valuation further comprises:
i) changing the account balance in the currency account by performing an account transaction, wherein the account transaction is transmitted to the digital currency system and recorded to the block chain transaction ledger by the network of decentralized computing devices; and
ii) adjusting the hedging position by the stabilizing account in response to the change in account balance in the digital currency account.

### Claim 14 (depends on 13)

The digital currency account stabilization method as recited in claim 13, wherein the step of adjusting the hedging position further comprises:
i) communicating the account balance change of the currency account to the stabilizing account; and
ii) one of: opening, closing, and partially closing by the stabilizing account at least one item selected from the group consisting of futures contracts, forward contracts, swaps, and derivatives.
