Billed as the mother of all cryptocurrencies, Bitcoin which is a decentralised digital currency was created by someone called Satoshi Nakamoto (possibly a pseudonym) in 2009. As with most cryptocurrencies, Bitcoin is 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, according to IANS report.
Each asset holds a value, often priced in U.S. dollars, which leads to another use case: trading and investing. Aside from stablecoins — which seek to stabilize the instability of cryptocurrencies by pegging an asset to something else, such as the U.S. dollar — most cryptocurrencies constantly fluctuate in price. You can trade between cryptocurrencies and national currencies (called fiat currencies) on exchanges, depending on the trading pairs available on the platform of choice.

Although you can create another private key and start accumulating cryptocurrency again, you can’t recover the holdings protected by your old, lost key.
