I Do not complain from here onwards.
You think Bitcoin was the only opportunity I had to invest at that time, no! There were several but you just think  about Bitcoin, anyway, maybe the reason not to invest was the right one, it was not yours to put money to the big thing, the mistake was not putting "something" that is the real error $ 1000, $ 2000 until only $ 500 were a great investment.

See you in 10 years, you will tell us your new experience.
