With the news that Vitalik Buterin - the co-creator of cryptocurrency Ethereum - has become the world's youngest crypto-billionaire and second youngest self-made billionaire of all time, you might be thinking to yourself, 'If only I'd managed to get into that a few years back.'
Well, it turns out that's a fair question, because if you had invested just $100 in the world's second largest cryptocurrency - by market capitalisation, anyway - not long after it started in 2015, you'd be sitting on a considerable chunk of cash.
Of course, if we all had wheels we'd be wagons. But it might interest you to learn exactly what that relatively small investment could have become over the years, if you'd have just got in early and then let it ride.
So, currently one Ethereum sits at a record high of $3,464 [at the time of writing] which works out to around £2,500.
However, back in the early days of the currency - August 2015 - one single unit would have only set you back $1.25.
That means that you could have bought 80 Ethereum for that aforementioned $100.
If you take the current market value, and multiply that by 80, your initial investment would today be worth a gigantic $277,120. That's more like £200,170.
Yep, we all really missed the boat on that one.
One person who definitely hasn't missed the boat is the aforementioned Vitalik Buterin.
His vast increase in net worth to around $1.15 billion seemed unlikely as recently as last year, when the value of Ethereum was hovering around the $100 or $200 dollar mark.
Since the end of last year, the price has skyrockets, meaning that his personal horde of 333,520 Ethereum is now worth a staggering $1,155,313,280 (£833,934,000).
Not bad, given that he's only 27 years old.
Buterin, according to Forbes, was born in a town outside of the Russian capital Moscow in 1994, before his family moved to Toronto when he was a child.
Before starting Ethereum he co-founded and wrote for Bitcoin magazine and received the prestigious Thiel fellowship - awarded by tech-investor and billionaire Peter Thiel - that gave him $100,000 to pursue interests outside of regular education such as university.
Around one year later, Buterin and his team devised Frontier, which they have described as the 'barebone implementation of the Ethereum project.'
He then helped to co-create the cryptocurrency in 2014.
Buterin is now the youngest cryptocurrency billionaire, as well as the second youngest self-made billionaire, behind Austin Russel, who founded Luminar Technologies in 2012 and became a billionaire at the end of last year aged only 25.
