I do not regret. I always thought that everything that happen in my life is experience. And failure is part of learning. So I fail today, I will get up and learn from my mistake. It is very naive, I guess. But I always try to not regret every decision in my life.

I do not regret because I have never use Bitcoins and never heard of it until 2013. I really like it and I want to earn it so bad. Until today, I have earn so much and always spend it straight to my bank account. I never use it to trading or invest it and keep it to my wallet. Because I think trading and investment is too risky to me. I think mining is better than investment. So I have to earn some more to get some mining rig.
