Blockchain and NFT

“The blockchain is an incorruptible digital ledger of economic transactions”

Cryptocurrency is a digital or virtual coin secured by cryptography, which makes it next to impossible to counterfeit.

A cryptocurrency or “crypto” is a digital currency that can be used to buy goods and services. It uses an online ledger with strong cryptography to secure online transactions.

Much of the interest in these unregulated currencies is to trade for profit, with speculators at times driving prices skyward.

They have their own store values and are designed to use as a medium of exchange for buying goods or services.

Cryptocurrencies are decentralized, meaning that no authority regulates them.

They are built on blockchain network technology, which ensures transparency and helps track every transaction.

So, cryptocurrency does not exist in physical form and is typically not issued by a central authority.

Because cryptocurrencies do not have an underlying economic base, they are inflation-proof, but not speculation-proof.

Also, the digital structure facilitates portability across the globe and offer transparency.

But, they are often criticized for the possibility of exchange rate volatility, and the vulnerability of the infrastructure underlying them.

Cryptocurrencies are digital currencies that use blockchain technology to record and secure every transaction.

A cryptocurrency can be used as a digital form of cash to pay for anything where it’s accepted…

They are tokens that can be used as a form of payment in exchange for online goods and services.

They have a pre-determined store value of their own, just like any other fiat currency like the US dollar or the Euro.

Cryptocurrencies are digitally mined, where computers solve complex computational mathematics problems.

Cryptocurrency is an alternate way of paying for goods and services.
