Yes, Bitcoin has changed many people's lives and their.you can estimate from the price of Bitcoin that when Bitcoin came into existence .its price was very low and slowly how much it increased its value.whoever invested in it at a low price is now millionaire and it is obvious that when a person becomes a millionaire, his lifestyle also changes.Anything or any investment takes time to change . If you think that I can become millionaires overnight by investing in Bitcoin that is wrong .And I have also seen many people who lose everything by investing in Bitcoin because they make short term investment in Bitcoin.
