That's a dumb user name "Learn Crypto"
Why would you need to learn crypto? it is a nearly meaningless term.
maybe you should learn bitcoin first in order that you can come to appreciate that crypto is largely a distracting, vague and meaningless word that seems to be used by people who either do not know anything about bitcoin or are purposefully or without purpose trying to create confusion by putting bitcoin into a meaningless category.
Some people don't know the difference between Bitcoin and altcoins because of a lack of information or misinformation. In other to deceive people to embrace or invest in their get-rich-quick shitcoin project, some of them crypto developers and promoters will hide behind Bitcoin. It is common to see them attaching Bitcoin and its logo on their advertisement channels to attract people to their project. In my early days of joining this sector, I attended a so-called Bitcoin awareness seminar, and nothing about the currency was discussed. The organizers kept persuading us to buy a worthless coin and telling us that it would be worth more than Bitcoin in less than one year. So when people especially newbies come up with names or discussions where they use vague words like crypto to discuss Bitcoin, I assume it was a result of misconceptions.
