I wouldn’t say that actually. In my experience, a lot of the Gen Z and Gen Y are interested and invest in cryptocurrencies and they are precisely the generation who are doing Fridays for Future etc. Of course, you can’t generalize either way, but I do believe there are many people who invest in altcoins and also care about climate change. That is also why I think a more energy efficient approach in the blockchain technology is due and that the currency which rises to that challenge, will be the next big thing in that field.
Yes, like I said a friend introduced me to it and also got me the invitation, which you need to do the tests, get verified and then be able to mine coins. Of course you can also skip all that and only invest, no need to do the validations if you would only like to buy some coins.
The test is split up in two parts plus one more task. For the short session you solve picture puzzles through logical thinking. So its 4 pictures and you have to bring them in the right order to make a story. You only have a few minutes to do it. Then there’s a long session where you do the same, but then also rate the puzzles on account of whether they have specific keywords in them and some other criteria. And then you also have to create a few new puzzles yourself, where you get random keywords assigned and have to make up a story using images from the web (or I think you might also use your own or draw something, not sure actually).
