Web3 and Cryptocurrency: How the two are connected

In the past, when you wanted to buy a product online, you would have to either use a credit card or a PayPal account. Today, cryptocurrency has emerged as a viable third option, with less expensive transactions and more anonymity than either of the established payment methods. Cryptocurrencies and their underlying blockchain technology have made it possible for financial products that were previously thought to be impossible. Cryptocurrencies incentivise running the network and all economic layers associated with it.
