I tried to convince my friends and family many times but at the end of the day it only wasted my time as none of them were interested in knowing bitcoins or investing their money in it as they have a feeling that bitcoin will not survive in long term.
yeah i also try to convince my on bitcoin but few of my friends are interested to join bitcoin and they are now using bitcoin for online shopping and they feel very easy and fast with bitcoin.
I will suggest that you have to tell them about the ways of earning of bitcoin to them so they will like to join bitcoin community because in now world almost all of the people want to have a source of income they want any way to earn money for their living and for their bright future. If you will tell them that in earning bitcoin you will not even go to outside to any office and you will earn from home then they will be more happy.
