> A Look at Low-Risk Ways to Learn Crypto 1. Don't. There are no non-scam use-cases for blockchain that don't have better non-blockchain solutions. 2. If you must, focus on implementing a toy blockchain in $LANG_OF_CHOICE. At least that way you get programming practice.

    Yes, my bad. 2 trillion. The value of companies that are doing business in the domain, e.g. Kraken, FTX should also be added to that value.

>There are no non-scam use-cases for blockchain that don't have better non-blockchain solutions. This is a classic. I can assure you that cryptocurrency has a use case, although you might not be interested in third world stories. You might be writing from a country where you are allowed to buy any currency you want. Maybe if you want to have euros, dollars, swiss francs, you name it, you can. In a bank account! It must be great living in a place [where people trust banks](https://en.wikipedia.org/wiki/Corralito https://en.wikipedia.org/wiki/Corralito). You probably are not forced to earn and save money in a currency that loses it's value by 50% every year. You are giving an opinion (and it's even plain wrong) without realizing how privileged and out of touch you are with the reality of a lot of people.
