Economics has always been complicated, but the day to day stuff was always pretty straightforward. Make money from working, exchange that money for goods and services, save a bit for a rainy day if possible.

The online world changed things. Not so long ago, people were afraid to give their banking details to eBay, now people trade in currencies they will never hold in their hands, and are investing in non-fungible tokens.

NFTs, put simply, are items that are unique and can鈥檛 be replaced with something else. In comparison, a coin would be seen as fungible - traded one penny for another and you still have something worth a penny. NFTs can be traded for different NFTs - like trading cards - or eventually sold off for cash when the owner thinks they can get the best price.

Until recently, NFTs have been mostly made up of digital art, some music, even a Jack Dorsey Tweet, but we鈥檙e on the cusp of a new era in digital economics, one where everything could be made into a token - the likes and comments you leave on social media, the hobby you dive into on your off time, even your heart, or your mind.

Aleks finds out how the digital economy has changed so much in the last decade, and explores a future where everything - from your likes, your hobbies, even your heartbeat - could be Tokenised and up for trade.
