You should look at the people who have made a profit from bitcoin to learn, not think that bitcoin can enrich everyone, or it will help reduce unemployment, reduce poverty as many people think.
I agree with what you have said that Bitcoin cannot fully help the economy, fix poverty and other economic problems as many people say. In fact, to be able to get the maximum profit in investing in Bitcoin is not that easy and not everyone can.
It is true that investing in Bitcoin can help someone's economy but it will not be so significant, it all depends on how much they invest and how well they sell it at a high enough price.
And it's true, in fact that many people also lose investing in Bitcoin because of their own mistakes, they can't understand the market and don't have good investment risk management.
Bitcoin is only a tool to be used to improve oneself. No one can help a person's situation but himself by utilizing the tool around him to improve his way of living. We have seen people who are into Bitcoin lost a huge amount of money and end up broke because someone had cheated on them and scam them of their investment.
At the end of the day, Bitcoin being a tool may help or worsen a person's financial state. After all, the decision made is not done by Bitcoin but the person who owns the body and the money.
