Not everyone has high confidence in Bitcoin.. just like you compared to one of your family members,... when you succeed in Bitcoin, and you suggest Bitcoin to your family members, don't forget about the risks that your family members might experience... their emotions are not the same as yours, so when you can't accompany what their needs are, and how their emotions are when they see their assets decrease in value, you will trouble yourself...
Make your own decision, by investing according to your wishes... those who want to invest in Bitcoin, please... those who refuse it are fine... even those who want to learn, please... there is no obligation in Bitcoin....
