I discussed the final investment decision directly with my family. People in my family don't know about Bitcoin but when I told them about Bitcoin and explained it to them for a while they got some idea about Bitcoin. I explained them about Bitcoin in such a way that they supported my investment. It's not like I misled my family into investing, I gave my family a real picture of Bitcoin investing which they really liked.
My family members have assured me that I am planning my future where other children take money from their parents and buy drugs and other bad things with that money. They were happy with my plan and said that they would help me financially or otherwise in terms of investment.
It is good that you have convinced your family members to invest in Bitcoin but have you told your family that investing involves risk. If you haven't informed them about this then you should discuss it with them and not just Bitcoin investment. I agree you are willing to invest in Bitcoin, have looked for money accordingly but you should think before investing and do proper planning and judgment analysis before investing. Many like you are interested in investing in the new state and even they want to invest with the help of their family.
It turns out that you are investing in Bitcoin and suddenly the price of Bitcoin drops when your family stops investing in Bitcoin for you. Will you be able to continue your bitcoin investment then.
