First of all, OP is a drama queen.
Second, same as everybody else, he lacked the balls to actually do something "substantial" when it was required.
What if I tell you that you would get $1m in 3 years if you invest $8k right now?
Would you do it? No you wouldn't!
That's exactly the reason why you wouldn't invest $8k in BTC in 2012.
Basically, you still have the same problem right now as you've had 3 years ago.
If I invest 8k today the price of the coin has to hit about 28k for me to become a millionaire. I don't see that happening.
Put 8k in a stocks that pays good dividends and is projected to increase in price, use dividends to reinvest in other dividend stocks and keep going until you get a nice quarterly bonus and use that for other styles of investment.
But i doubt you could get a stock account as you're probably too young.
