My cousin who in time i asked to investment on bitcoin but has always had excuses that he'll invest later, sometimes he tells me that he's afraid to invest his money on the bitcoin due to the potential losses.
Basically, you don't need to ask your cousin to invest in Bitcoin. You only can help him if he is interested in Bitcoin himself. If you ask him to invest, you will take the responsibility if your cousin fails in his Bitcoin investment in the future. I believe you don't want to be blamed if there is something bad happening in your cousin Bitcoin investment.
Someone should be optimistic and brave enough if he wants to invest in Bitcoin. If your cousin is afraid, it means he is not ready to deal with the risks in Bitcoin investment. So, it is better to give the time for your cousin to learn more about Bitcoin investment first.
He had aslo told me that he's contented with his monthly salaries at then but now he has fall back to me that he's ready to invest because he has lost his job and it's becoming tough for him to meet up with his financial requirements.
If he lost his job, how he can have the funds for investment?
Investment isn't the priority if someone has no income. It is better to have a job first and make sure to have good salary. When your cousin has free money for investment monthly, you can let him to buy Bitcoin. We must know that taking profits from Bitcoin mostly not in a short time, it will take a long time. He can expect to get profits monthly from Bitcoin. Moreover, your cousin is a beginner.
