Dogecoin is a fun, new and rapidly growing form of digital currency. This form of digital currency is called “cryptocurrency”; a type of digital currency. Cryptocurrency is completely anonymous, decentralized, and extremely secure.
To use Dogecoin, you need a wallet. A wallet is essentially an address you use to receive Doge. Whenever you acquire a new wallet, a private and public key is generated and given to you.
The public key can be freely shared and is what people use to send Doge to each other. This public key is stored with the amount in the currency's transaction history, known as the block chain. By looking at the block chain, you can determine how much Doge an account has by adding up how much was sent and received to that account.
However, the private key should be kept secret as whoever knows the private key claims ownership of all its associated funds (in fact, by default the local wallet hides the private key from you so you don't accidently reveal it). Whenever you back up a wallet, you actually aren't saving how many coins you have, but the private key. This way, you can't spend coins then restore from a backup to regain them. Instead, the private key is used to just claim ownership of all funds associated with its public key pair in the block chain.
The community is very fun and positive. Not very Wall Street. Anyone is welcome, even new shibes (Shiba Inus) like you. There are also many community efforts, such as the recent 30k USD worth of Doge donation to the Jamaican Olympic bobsled team. To meet fellow shibes, check out reddit.com/r/dogecoin. Everyone is very generous and tipping is a core part of the culture.
