In my own opinion, bitcoin and blockchain technology can help a county to grow and be successful. For an individual, they can help financially. Let's just say I am an example of this. Last year, the whole 2017, I was drowning in debt. Many things happened to me and my family that's why I was forced to lend some money. My cycle, debt-salary-pay bills and debt-short-debt. It is just like that. But when I earned because of my investment, I paid all my debts and now, I am debt-free and can spend all the money to my family.
