Yes, it is true that Bitcoin has changed the lives of many people, but more importantly, it has also changed people's attitude towards the nature of money.
Bitcoin has changed people lives in two senses, firstly, some people got a lot of money through bitcoin, and through trading I can say, and secondly it has changed many people lives in a negative way, do you know how?
The negative affect of this has been a lot of people has invested their money in trading and in return the had been in loss, after taking loans and too many money from their relatives, friends etc., and after all these they got intro depression and are facing a lot of problem. This is an example of a person in my country who is suffering from it.
