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.
Never spend time in convincing other if they are not interested to know about anything particular,it is a waste of time and energy.You will get many questions and skeptic views from everyone because they could not comprehend about how something which is virtual is having a value will be the biggest question everyone is having and it is not possible to give a reasoning for all these people.
Yeah I tried to explain it to people around me but after knowing that they are not interested in knowing anything about bitcoins I stopped to waste my time behind them as I can invest that valuable time online which will help me in earning some more amount of bitcoins.
