On a blockchain, mining is the validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized hardware such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and scrypt. This arms race for cheaper-yet-efficient machines has existed since bitcoin was introduced in 2009. Mining is measured by hash rate, typically in TH/s. A 2023 IMF working paper found that crypto mining could generate 450 million tons of CO2 emissions by 2027, accounting for 0.7 percent of global emissions, or 1.2 percent of the world total

While securities are in place, that does not mean cryptocurrencies are un-hackable. Several high-dollar hacks have cost cryptocurrency start-ups heavily. Hackers hit Coincheck to the tune of $534 million and BitGrail for $195 million, making them two of the biggest cryptocurrency hacks of 2018.

If you want to use cryptocurrency to buy products and services, you will need to visit a cryptocurrency exchange. These are businesses that allow you to buy or sell cryptocurrencies from other users at the current market price, similar to a stock.

Investing in cryptocurrencies is a little different than investing in shares of a company. Stock represents ownership of a business and a claim to profits the company generates. Purchasing coins of a cryptocurrency, though, is a speculative bet on the price movement of that digital currency — which can be highly volatile and is subject to the law of supply and demand since digital currency by itself is not a dynamic asset. Cryptocurrencies can be exchanged for other digital currencies or for fiat currencies like the U.S. dollar using a digital wallet on a trading app.
