You're very correct, Bitcoin is not mainly for the rich, it's core principle, which simply means that anyone with internet connection can participate, I agree with you that mindset matters alot but financial ability matters just as much, someone who is wealthy can afford to take risks, and even lose money without life changing repercussion. But someone with low income can't. Bitcoin isn't built for the rich, nor restricted by status. As long as you have internet connection you can participate regardless of your background or status.
Bitcoin investment is open to everyone, it is not for any specific class. Rather, those who can afford it, he can invest here, it is an independent currency, if you invest here, there is no loss and no profit to me and others, and if you do not invest here, there is no loss and no profit to me and others, the matter of profit and loss here is completely your personal, if you invest, you will have the opportunity to profit in the future, and if you do not invest, you will be deprived of this opportunity, so it depends on everyone's personal wishes, but the main thing is that everyone is open to investment here.
