Well, bitcoin makes things run efficiently. having to pay through bitcoin which is the first decentralized currency in the world will help people with ease.  which means it is a benefit for everyone and that is a another way to live better but it could make people lazy due to the so much exposure to the internet and right now that bitcoin is getting popular and spreading from business to another business. They might just live their like sitting in a expensive chair surfing through the net and buying things through bitcoin. that is the only drawback i can think of.
