You cannot become rich with bitcoins if you have limited bitcoins in your wallet as you cannot expect that its price will be in millions in future so if you want to become rich with it then you need to accumulate very high sum of bitcoins which is not easy especially if you are earning it as earning will give you limited amount of bitcoins and not possible to buy more at current price as its not affordable for majority of us.
Being rich with Bitcoin could be, for example me. I also have a dream to improve my family's economy and I want to be rich because of Bitcoin. But to make it happen, of course not easy. If we want a lot of profit, we must provide a lot of capital and a lot of time. We must patiently wait for several years and stay calm despite the decline in prices. Let's say you want a profit of $ 10,000 to make it happen, you have to collect money for $ 1,000. And you have to wait for several years to double as much as 10 times. And if you want more profit, you have to raise more capital.
Along with our dream to be rich in bitcoin, we also have to realize that we will not reach at that level if we will not gonna risk money.
Investment is necessary and you can only do that if you have enough savings because investing is risky and it's important to invest what you can afford to lose.
