Speaking of bitcoin, bitcoin has helped my life, especially in my family's current economy, which I can tell very well from before, and I regret a bit because I know a few new bitcoins a few years, if only I knew bitcoin from scratch maybe now I already a millionaire 
I agree with that I actually reject Bitcoin at first since, when it's about money we can trust no one, it has been the system from first day, and I think that makes the society a very risky place which involves scams and anything that involves money laundering, and when I entered Bitcoin, I feel that I was enlightened that even at young age I can be able to have my own profit.
