For beginners, you dont necesarrily needed to learn everything about it, most of the time you just need to understand how it works, I always remember a dialogue on a movie something about you dont need how to learn how the machine for example actually work you just need to understand how it works and you can use fully used it, like if you have a refrigerator you dont need to know the board, how they assemble the circuits etc. all you need to do is how to used it. Unless you're a technician or something, or you repair something like that.
So for beginners they could start as long as they know how it works already, but as a beginner start with a low amount to minimize the mistakes, for me it is surely inevetable to avoid the mistakes, and also even better if you make one because that is where you can actually learn, We dont necesarrily need the crypto education but it is just nice to have one if you want to go deeper to understand the technology behind crypto and blockchain.
Yes, that's right. The examples you provided are also very easy to understand. To start trading or investing, especially for beginners, you don't need to learn the technical details (though it's better if you do). They only need to learn the basics, such as various crypto terms, fundamentals, and wallet security.
There are many terms in crypto, and they need to understand them to avoid trading or investing blindly. For example, Web3 is an internet term/concept, Blockchain is a digital data recording technology, Bitcoin is the first cryptocurrency, Altcoins are cryptocurrencies other than Bitcoin, dApps = decentralized applications, Wallets are digital wallets for storing assets, Private keys are the secret keys to asset owners, Stablecoins are crypto with stable values, Bull markets are rising market prices, Bear markets are falling market prices, and many others. I mean, these terms need to be learned to help them avoid unwanted risks.
