Early uses of money go back to 5000 years ago, but i think the first time in 5000 years a bit of a revolution is happening with money and how we pay for goods.
Last few years there have been a rise in online shopping/online payments, last few years there have been many high street closures and we see many businesses now trading solely online, then we have cryptocurrencies and due to covid there seems to be a push to stop using the unhygienic use of physical money and for people to pay for goods by card or online.
I think investing in money/online payments is one of the best investment people can make right now.
That was my way of thinking when I recently invested in one of the biggest single word financial domains on the market in .com.
