Cryptocurrency
Great minds.
:cool: I jumped in in July. I don't know if I'd want to write 15 minutes worth of spiel about Bitcoin, but there's a couple of important things about it. First of all, it's based on an important technology that has a multitude of use cases, i.e. the blockchain. Secondly, it's a currency that can be transmitted securely, quickly, cheaply, and globally. Thirdly, it's a store of value, a digital gold, and a great potential hedge against inflation. Fourthly, it's the granddaddy of a whole tribe of so-called altcoins, including a world computer called Ethereum on which the nascent field of decentralized finance is largely based through the use of smart (i.e. self-executing) contracts built on its protocol that remove the need for financial middlemen, such as banks. This in itself is huge. Loads more to say, but for now...
(BTW if you want some resources or advice, PM me as I'm a little ahead of you and have been diving right in.)
