This is indeed an interesting topic. It makes Forex look like a snail by comparison with the “hares” of the crypto-currency world. Before 1May2020 I knew absolutely nothing about crypto, but had some time on my hands to start learning. Three months later I am invested in eight crypto-currencies, the (very small) portfolio gain is something I find hard to believe, beginner’s luck, and I am now committed to creating a crypto investment portfolio ten times the size of the initial undertaking, and at a later stage when I know enough about it, to add a component of “crypto trading” to that investment account.
Crypto (and more specifically DeFi) is also referred to as “Internet 3.0”. As someone who has spent a good 20 years of my life in telecommunications networking, and more specifically in inter-networking protocol, it was like a huge light bulb moment for me after the first hour of “Youtube education” and I have not looked back. There are already over 50 “sectors” identified for DeFi, and just one of those sectors - interbank currency payments - has about 20 trillion dollars tied up in funds waiting up to 3 days to clear transactions, that DeFi could reduce to just billions by only tying up funds for the time it takes to add a block to the blockchain (minutes).
One other sector (yes, just one) is the Internet of Things, where the “things” will outnumber human beings very shortly. Trust between parties will be a thing of the past (decentralized voting models) and interoperability protocols will grow faster than we can imagine (re CRO, LINK, TRX, etc) and on top of those interoperability protocols will evolve end to end “apps” just like the OSI seven layer network model is today.
I don’t think you have to know anything about how it all works under the bonnet, but for me it sure helps to know a little of what’s going on.
