Data current as of Jan. People invest in cryptocurrencies for a variety of reasons. Here are some of the most popular:. Supporters see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, presumably before they become more valuable.

Some supporters like the fact that cryptocurrency removes central banks from managing the money supply, since over time these banks tend to reduce the value of money via inflation. Cryptocurrencies may go up in value, but many investors see them as mere speculations, not real investments. The reason? Just like real currencies, cryptocurrencies generate no cash flow, so for you to profit, someone has to pay more for the currency than you did.

Contrast that to a well-managed business, which increases its value over time by growing the profitability and cash flow of the operation.

Bitcoin and other cryptocurrencies have been anything but stable through much of their history. By December , it was trading at record levels again. This price volatility creates a conundrum.

But beyond those concerns, just having cryptocurrency exposes you to the risk of theft, as hackers try to penetrate the computer networks that maintain your assets.

One high-profile exchange declared bankruptcy in after hackers stole hundreds of millions of dollars in bitcoins. Cryptocurrency is an incredibly speculative and volatile buy. Stock trading of established companies is generally less risky than investing in cryptocurrencies such as Bitcoin.

Cryptocurrencies

A cryptocurrency , crypto-currency , or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank , to uphold or maintain it. Individual coin ownership records are stored in a digital ledger , which is a computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. In a proof-of-stake model, owners put up their tokens as collateral. In return, they get authority over the token in proportion to the amount they stake. Generally, these token stakers get additional ownership in the token over time via network fees, newly minted tokens or other such reward mechanisms. Cryptocurrency does not exist in physical form like paper money and is typically not issued by a central authority.

With a fleet of nodes or a pool, a group of individual miners can combine computational effort, dubbed hash rates, to win block rewards and split the earnings according to contribution. Blockchains require a protocol for achieving a decentralized consensus to verify the integrity of new blocks, and in crypto mining, this consensus mechanism is proof-of-work PoW. By contributing computational effort to validating transactions, miners receive a predefined amount of the coin for their proof of work.
