Because of the lack of knowledge to invest in bitcoin make bitcoin not for everyone.
I completely disagree with your thoughts, not only bitcoin but any investment, job or field with no knowledge, what can you do? You will not be able to do anything anywhere without knowledge, knowledge is a must if we want to start anything.
Bitcoin is for everyone, but whether people embrace it or not depends on each person. Like the saying goes, "when people really want something, they will definitely find a way", as long as they have determination, they can do it.
Many people have the misconception that bitcoin is only for tech-savvy people. That's not true, Bitcoin is for everyone, even those who know nothing about technology, as long as they have passion and are eager to learn, technology is not a barrier.
Yes, I agree with you, @Marvell1. @Mate2237 got it all wrong on this. Knowledge is the most important thing in everything one is doing, whether Bitcoin or not, even in our social life. If one doesn't have the knowledge to do things at the right time, that means the thing that is done at the wrong time is a total waste of time. Knowledge will help one know how to do something at the right time, but if one doesn't have the knowledge, the person will do what he wants at the wrong time, just like knowing that Bitcoin is for everyone but they don't want to take advantage of it. Without knowledge, one won't know that Bitcoin is for everyone or even if the person does know that Bitcoin is for everyone, the fear of risking their funds, the person will not take advantage of it.
Satoshi created bitcoin with decentralized nature and even he couldn't control it, which means he wanted to create it for everyone, who loves freedom and respects their privacy. Just like wealth, no one can stop us from becoming rich except ourselves. If we are lazy, do not make efforts, and refuse to accept challenges and risks, how can we become rich? Clearly, we are making ourselves become barriers for ourselves.
If we don't know, let's learn. If you can't learn it yourself, ask someone else to teach you. If others don't teach you, find someone else. As I said, if we really want it, we will always find a way to achieve it, it's all just an excuse for our laziness.
