That is sound advice. Can you provide some resources to do that?
Because this “space” is the Wild West that is more difficult to do than with stocks.
But, the web is full of resources. I would start with understanding the top two: Bitcoin/ETH. Learn the difference between POW and POS. Understand the scarcity components of each. Learn about smart contracts. Learn which ones were created as a joke (If it has “dog” in the name…it’s probably a joke.)
Learn how you have to buy them. It’s not always easy.
There are too many to research. So, I would stick to the market leaders for their type. But, the top ten or so are probably not going up 3,000% next week. So…there is a trade off.
