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.
Yes its absolutely right that invest only upto that extent which you can afford to loose. Crypto is highly volatile and can change the financial position of a person in few hours. Crypto can make you rich in a very short time and on the other aspect it may make you poor. So don't take such type of poor decisions like selling your property for investing in crypto. This is a very wrong approach , it can even ruin you.
