There is a popular saying that invest only what you can afford to loose. Some people are making the mistake of investing all their life savings into crypto and other ventures. Some people even went as far as borrowing money or even using their properties as collaterals to borrow money so as to invest into crypto. This is a wrong idea and it might cost you a lot.
Every investment has its risks. So consider the the risk involved by taking each step at a time and do not jump in once.
All those people are doing that because they were deceived with the wrong information, and made to believe that Bitcoin is some kind of money making machine. They think that you dont have to do anything but just invest your money and leave it there and it will continue to grow and whenever youre satisfied you can do the withdrawal, but thats not how it works.
