Many people have less idea about investment and more blind faith, but it is not good for us to have blind faith in anything. If we have enough idea about investment before investing and invest our money according to the words of others, then we will not get any confidence at all by investing and every time the investor will feel that he has invested all his money, whether it will be a profit or a loss. Another disadvantage of investing by relying on others is that when the market is a bit negative, that investor will get excited and will blame the person from whom he learned about the investment for his investment. Therefore, before starting investment, every investor should first know about the investment and he should also make sure in which coin he will invest.
