What is cryptocurrency
If you want exposure to the crypto market, you might invest in individual stocks of crypto companies. “There are also a few Bitcoin mining stocks such as Hive Blockchain (HIVE),” says Zeiler. “If you want some crypto exposure with less risk, you can invest in big companies that are adopting blockchain technology, such as IBM, Bank of America and Microsoft.”
Bitcoin has been characterized as a speculative bubble by eight winners of the Nobel Memorial Prize in Economic Sciences: Paul Krugman, Robert J. Shiller, Joseph Stiglitz, Richard Thaler, James Heckman, Thomas Sargent, Angus Deaton, and Oliver Hart; and by central bank officials including Alan Greenspan, Agustín Carstens, Vítor Constâncio, and Nout Wellink.
Variable renewable energy power stations could invest in bitcoin mining to reduce curtailment, hedge electricity price risk, stabilize the grid, increase the profitability of renewable energy power stations and therefore accelerate transition to sustainable energy.
Most cryptocurrencies are based on blockchain technology, a networking protocol through which computers can work together to keep a shared, tamper-proof record of transactions. The challenge in a blockchain network is in making sure that all participants can agree on the correct copy of the historical ledger. Without a recognized way to validate transactions, it would be difficult for people to trust that their holdings are secure. There are several ways of reaching “consensus” on a blockchain network, but the two that are most widely used are known as “proof of work” and “proof of stake.”

Cryptocurrency wallet
Early crypto users would write or type their keys on paper, which they called paper wallets. These evolved to include the keys and QR codes so wallets on mobile devices could scan them. However, paper wallets are easily damaged or lost, so many crypto owners do not use them anymore.
There are two main types of wallets: custodial and noncustodial. Custodial wallets (also called online wallets) are hosted by a third party that stores your keys for you. This could be a company that provides enterprise-level data security systems businesses use to preserve and secure data. Some cryptocurrency exchanges offer custodial wallets for their customers. Noncustodial wallets are wallets in which you take responsibility for securing your keys. This is the type that most cryptocurrency wallets on devices are.
BIP39 proposed the use of a set of human-readable words to derive the master private key of a wallet. This mnemonic phrase allows for easier wallet backup and recovery, due to all the keys of a wallet being derivable from a single plaintext string.
The safest crypto wallet has no connection on its own or to a device with internet access. It also should not deny you access to your crypto because a custodian has financial issues. Many so-called “safe” wallets have wireless connection technology that determined cybercriminals can access.
A wallet can also have known or unknown vulnerabilities. A supply chain attack or side-channel attack are ways of introducing vulnerabilities. In extreme cases even a computer which is not connected to any network can be hacked.
