Just as important as investing in bitcoin one should have a fair understanding of bitcoin and be careful. All parents like to make sound decisions about what to do when the market goes bad, investments fail business goes bad. That's why you have to know about the risks first and make sure and then take the right decision. Don't give money unless parents and cousins are sure to give money.
Cousins? To be honest, I don't think it's a great idea to let anyone know about your investments or make financial suggestions or recommendations because we live in a time where you won't get appreciated for the good you do but you will be discriminated for the bad that you didn't even intend to do. What I mean is that if you suggest cryptocurrencies to someone who doesn't have any idea about them and if they go ahead and make an investment only after you tell them, you will need to face the consequences in case they lose their money.
If they buy a cryptocurrency that isn't good because they don't know how to do research or anything, and then when the price of that coin drops or if the project fails, they will blame you for their loss. So it's better that you don't do such things and only keep these things within the family if you know your family members understand you well.
