Numerous companies developed dedicated crypto-mining accelerator chips, capable of price-performance far higher than that of CPU or GPU mining. At one point, Intel marketed its own brand of crypto accelerator chip, named Blockscale disk genius review.
Cryptocurrencies have become a popular tool with criminals for nefarious activities such as money laundering and illicit purchases. The case of Dread Pirate Roberts, who ran a marketplace to sell drugs on the dark web, is already well known. Cryptocurrencies have also become a favorite of hackers who use them for ransomware activities.
Such large amounts of money in cryptocurrencies have attracted the attention of thieves. An early, spectacular theft occurred in February 2014, when Mt. Gox, the world’s third largest Bitcoin exchange, declared bankruptcy because of the theft of about 650,000 Bitcoins, then valued at about $380 million. The largest cryptocurrency hack happened in 2025, when $1.4 billion in Ethereum was stolen from the Bybit exchange. Evidence pointed to the Lazarus Group of North Korean hackers as being behind the Bybit theft. (The Federal Bureau of Investigation had previously identified the Lazarus Group as the culprits in a 2022 cryptocurrency heist of $614 million.)
First, you need a cryptocurrency wallet, which is a digital wallet similar to a digital bank account, allowing you to receive, send and store cryptocurrencies. There are various wallets to choose from:
Various studies have found that crypto-trading is rife with wash trading. Wash trading is a process, illegal in some jurisdictions, involving buyers and sellers being the same person or group, and may be used to manipulate the price of a cryptocurrency or inflate volume artificially. Exchanges with higher volumes can demand higher premiums from token issuers. A study from 2019 concluded that up to 80% of trades on unregulated cryptocurrency exchanges could be wash trades. A 2019 report by Bitwise Asset Management claimed that 95% of all bitcoin trading volume reported on major website CoinMarketCap had been artificially generated, and of 81 exchanges studied, only 10 provided legitimate volume figures.

Crypto market capitalization or “crypto market cap” for short is a widely used metric that is commonly used to compare the relative size of different cryptocurrencies. On CoinCodex, market cap is the default metric by which we rank cryptocurrencies on our frontpage. We also track the total cryptocurrency market cap by adding together the market cap of all the cryptocurrencies listed on CoinCodex. The total market cap provides an estimate on whether the cryptocurrency market as a whole is growing or declining.
The very first cryptocurrency was Bitcoin. Since it is open source, it is possible for other people to use the majority of the code, make a few changes and then launch their own separate currency. Many people have done exactly this. Some of these coins are very similar to Bitcoin, with just one or two amended features (such as Litecoin), while others are very different, with varying models of security, issuance and governance. However, they all share the same moniker — every coin issued after Bitcoin is considered to be an altcoin.
Play-to-earn (P2E) games, also known as GameFi, has emerged as an extremely popular category in the crypto space. It combines non-fungible tokens (NFT), in-game crypto tokens, decentralized finance (DeFi) elements and sometimes even metaverse applications. Players have an opportunity to generate revenue by giving their time (and sometimes capital) and playing these games.

Bitcoin introduced a type of currency (called cryptocurrency) that can be created and tracked on a public ledger (called blockchain), and which is not controlled by any central authority like a company or a country. Unlike with traditional currencies, everyone who can contribute the computational power needed to maintain this network will keep a record of every single Bitcoin transaction. In return, these participants will be able to gain Bitcoin by mining, which is the process of validating transactions being added to the ledger by solving complex puzzles. This is called the proof of work (PoW) consensus algorithm.
