Until now, bitcoin has been virtually synonymous with blockchain technology. This year, the NFT has been added as a synonym.
Like bitcoin, an NFT is a token on the (respective) blockchain.
All coins and tokens stand for predefined values. These can be money-like values, but also values such as ownership or participation rights.
The money-like tokens or coins are exchangeable 1 to 1.
1 Bitcoin = 1 Bitcoin. They are „fungible“.
The NFT, on the other hand, is the Non-Fungible Token, not exchangeable.
