Bitcoin is a cryptocurrency and a payment system, first proposed by an anonymous person or group of people under the name Satoshi Nakamoto in 2008. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network.

Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

Bitcoin is a decentralized currency that uses cryptography to secure transactions and control the creation of new units of the currency. Decentralized means that it is not subject to government or financial institution control.

Cryptography is used to secure the transactions and to control the creation of new units of the currency. The first Bitcoins were created in 2009 as a reward for solving a complex mathematical problem.

Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.

As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.

Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain.

Bitcoin is unique in that there are a finite number of them: 21 million.

The term “bitcoin custody” has been used in a variety of ways, but it generally refers to the safekeeping of bitcoin. This can be done through a third party, such as a cryptocurrency exchange, or it can be done through a self-custodial wallet.

When bitcoins are held by a third party, they are said to be in “custody.” The custodian is responsible for keeping the bitcoins safe and secure.

They may also offer other services, such as allowing the owner to trade their bitcoins or providing a platform for buying and selling bitcoin.

Self-custody means that the individual is responsible for keeping their own bitcoins safe. This can be done by storing them in a secure wallet, such as a hardware wallet.

Bitcoins can also be stored on paper wallets or on USB drives. These are considered to be cold storage methods, as they are not connected to the internet and are therefore less vulnerable to hacking.

The main advantage of using a custodian is that it offers security and peace of mind. The custodian is responsible for keeping the bitcoins safe, so the owner does not have to worry about them.

Another advantage is that custodians often offer other services, such as allowing the owner to trade their bitcoins or providing a platform for buying and selling bitcoin.

The main disadvantage of using a custodian is that it adds another layer of complexity to the process of owning and using bitcoin. The owner must trust the custodian to keep their bitcoins safe and secure.

They also have to rely on the custodian for other services, such as trading or selling their bitcoins. If the custodian goes out of business or is hacked, the owner could lose their bitcoins.

Self-custody eliminates these risks by giving the owner full control over their own bitcoins. However, it also comes with its own set of risks, such as losing access to your coins if you lose your wallet or forgetting your password.
