Since the beginning of last year, we often hear about NFT. Regularly, celebrities invest huge sums in what are often presented as simple JPGs representing computer generated characters. for example, Famous rapper Eminem bought NFT From the Bored Ape Yacht Club collection for $450,000.

One Euro can be exchanged for one Euro. Similarly, Bitcoin can be exchanged for another Bitcoin.
