Non-fungible tokens (NFTs) have quickly become all the rave for tech-minded investors, but most Americans don't understand how they work -- or more importantly, what they really are. Sure, they are digital copies of original documents, artwork, music, games, etc., but few see their value.

Still, NFT’s are gaining in popularity, no matter what people think of them. By understanding their unique value, serious investors are finding more benefits to owning them, especially with the unstoppable rise in the price of Bitcoin. Savvy investors can boost their portfolios by taking part in a growing digital economy while owning a piece of art, music, or games.
