Most people have the same reason why they buy crypto, that is to earn profit and to change financial to be better , although i dont not understanding how blockchain technology work but crypto and this technology has potential to change amillion financial's people in the world. Since Bitcoin created and tradeable in that times more milyuner was born from crypto.
You're right, even I am like that. I don't really understand this system, but I can use it. of course that is all to get a better profit, and improve the economy that I have. well, because of that, most people buy crypto to try to use it to get a good profit.
Sometimes, I still find it a bit hard to believe that people could be a part of a system, and they really do not care about the system or do not even want to bother to understand it, which is one of the reasons why we will keep seeing those who are just so keen about trying to only make something out for themselves in the short term and never be able to focus on long term.
Buying cryptocurrency should be because you actually know what you are getting into and what you are holding in terms of its potential and what makes it tick for the long run.
