The biggest risk in life is not taking any risk, investing is risky, it has been said before, but if you cannot take this financial risk, then how can you think about success. If you look at the background of those who are successful, you will see that they have come to this stage by taking risks. Elon Musk may be the biggest example of this, even after failing to launch a rocket several times, he did not stop, but he took more financial risks and tried again, as a result of which he finally achieved success.

Initially, let's assume that an investor, instead of investing in Bitcoin, starts another business with his money or keeps his money in the bank.
If he starts another physical business, he will definitely get a profit there, but there is no guarantee of that, but rather the money he will spend on the goods he will buy for the business is a kind of risk. Again, those who keep money in the bank do business with their money, but even then, many times it is seen that many people do not get their deposits back due to bank bankruptcy. 
So I think we should trust Bitcoin without worrying too much and plan long-term investments in Bitcoin.
