An investor should always focus on increasing his source of income. But it is not possible to increase the source of income in every field, so the investor should invest as much as he can. Try to do something new and do something alternative to increase the source of income. An investor should be careful at every step, so that their situation does not get so bad that it will affect their daily life for investment.
Investing is completely up to you. However, if you have firmly decided to earn money through investment, then it will be best for you to adopt the DCA method. The more you hold patiently, the better the investment will be. Your investment depends on income and expenditure.
