Because of the story that "bitcoin can make us all rich", people often have unrealistic expectations and expect to become rich overnight.
I would say that bitcoin is just a means or a tool, but if we don't know how to use it well, it won't help us achieve our financial and other goals.
Without hard work on yourself, learning and research, planning and developing a strategy and a basic understanding of the crypto market, it is not realistic to expect any concrete results and earnings on btc.
Bitcoin can make all of us rich only if we follow the right strategy. Don't think that we can blindly invest in Bitcoin and will become rich in few days. Bitcoin no doubt is one of best investment of current time but it need our time and proper research. Without right strategy it will be difficult to get desired results from Bitcoin. There is lot of info available online through which we can increase our knowledge about Bitcoin and one key principle for success with Bitcoin is to think of long term investment.
I agree with you, after all, Bitcoin investment will never guarantee us a profit, if we invest, our success is never guaranteed, but there is always a risk involved. So we must know the success of Bitcoin investment as well as its risks, because success is not guaranteed. Many new investors think that it is possible to get rich quickly by just buying Bitcoin, but in reality the market is not that easy. Bitcoin always fluctuates with uncertainty, and those who invest greedily without sufficient research only in the hope of profit, panic and sell during that instability, from which they have to face losses. So instead of being blind and greedy, we should invest with reality, and be aware of the risks in advance.
