Bitcoin, often called digital gold, is the world’s first cryptocurrency and the most recognised name in the blockchain industry. Created by the pseudonymous Satoshi Nakamoto in 2009, Bitcoin introduced the concept of a decentralised digital currency that operates independently of governments and financial institutions. Today, it is the largest cryptocurrency by market capitalisation and a cornerstone of the digital asset ecosystem.
Bitcoin has survived multiple bear markets, regulatory scrutiny, and technological challenges, maintaining its dominance. This resilience makes it a reliable investment choice, especially for newcomers to crypto.

For lucky miners, the Bitcoin rewards are more than enough to offset the costs involved. But the huge upfront cost is also a way to discourage dishonest players. If you win the right to create a block, it might not be worth the risk of tampering with the records and having your submission thrown out — forfeiting the reward. In this instance, spending the money on energy costs in an attempt to tamper with the historical record would have resulted in significant loss.
Proof of stake systems have some similarities to proof of work protocols, in that they rely on users to collect and submit new transactions. But they have a different way of incentivizing honest behavior among those who participate in that process. Essentially, people who propose new blocks of information to be added to the record must put some cryptocurrency at stake. In many cases, your chances of landing a new block (and the associated rewards) go up as you put more at stake. People who submit inaccurate data can lose some of the money they’ve put at risk.
Proof of stake is another way of achieving consensus about the accuracy of the historical record of transactions on a blockchain. It eschews mining in favor of a process known as staking, in which people put some of their own cryptocurrency holdings at stake to vouch for the accuracy of their work in validating new transactions. Some of the cryptocurrencies that use proof of stake include Cardano, Solana and Ethereum (which is in the process of converting from proof of work).
Proof of work is one way of incentivizing users to help maintain an accurate historical record of who owns what on a blockchain network. Bitcoin uses proof of work, which makes this method an important part of the crypto conversation. Blockchains rely on users to collate and submit blocks of recent transactions for inclusion in the ledger, and Bitcoin’s protocol rewards them for doing so successfully. This process is known as mining.
After people realized the barter system didn’t work very well, the currency went through a few iterations: In 110 B.C., an official currency was minted; in A.D. 1250, gold-plated florins were introduced and used across Europe; and from 1600 to 1900, the paper currency gained widespread popularity and ended up being used around the world. This is how modern currency as we know it came into existence.
Many cryptocurrency projects are untested, and blockchain technology in general has yet to gain wide adoption. If the underlying idea behind cryptocurrency does not reach its potential, long-term investors may never see the returns they hoped for.

One feature of the Bitcoin system is that the supply of Bitcoins increases at a pre-determined rate and is capped at around 21 million (with each bitcoin able to be subdivided into 100 million satoshis or 0.00000001 bitcoins). Because of this, the supply of Bitcoins has been commonly compared to the supply of a scarce commodity, such as gold.

Cryptocurrency has gained a lot of traction among investors over the last few years. Bitcoin, the most well-known type of cryptocurrency, hit a 5-year high in November 2021 — so it’s understandable for anyone to want to snap up this in-demand digital cash.
It is true that cryptocurrencies are not under the control of a central authority. Even though many countries are seeking to regulate the use of cryptocurrencies, they remain, by their very nature, decentralised.
