Every cryptocurrency transaction is recorded in a public ledger known as the blockchain, which is the technology that makes it possible for it to exist. This allows people to follow the history of cryptocurrencies like Bitcoin to prevent them from spending coins they don't own, copying transactions, or undoing them. Because blockchain intends to eliminate intermediaries such as banks and internet marketplaces, there are no transaction costs. What can I do with bitcoin? In recent weeks, I spoke with nearly two dozen people in, adjacent to, and critical of the crypto space about what they envision to be the purpose of crypto. What emerged was a picture that was simultaneously murky and clarifying, in that there’s not one good answer. Some of what it does is promising; a lot of what it does — even boosters admit — is trash, and trash that’s costing some people a lot of money. This probably isn’t the death knell for crypto — it’s gone through plenty of boom and bust cycles in the past. It would be unwise to definitively say that crypto has no chance of being a game changer; it would also be disingenuous to claim it is now.
Cryptocurrency is a digital payment system that doesn't rely on banks to verify transactions. It’s a peer-to-peer system that can enable anyone anywhere to send and receive payments. Instead of being physical money carried around and exchanged in the real world, cryptocurrency payments exist purely as digital entries to an online database describing specific transactions. When you transfer cryptocurrency funds, the transactions are recorded in a public ledger. Cryptocurrency is stored in digital wallets. What is cryptocurrency used for? The newness of cryptocurrencies makes their risks not easily understood, which translates into a poor understanding of how cryptocurrency values correlate with the values of other assets. Not enough historical data exists to confidently predict how the prices of cryptocurrencies fluctuate when the prices of other assets change. This lack of visibility creates an obstacle to establishing a balanced portfolio that maximizes returns without exceeding your desired level of risk.
