Well no time to be regret about not believing to it way back then. The thing is i'm now doing bitcoin thus forget the negativity and just focused in it. We cannot do about the past but we can do for our present that will lead to our future good life. May the force be with us! 
thats right, i think rather than continue to regret what has happened better focus on what will happen mate, you know that bitcoin prices will continue to grow and why do not you try to forget your sadness and do real actions like buying and collecting bitcoin? it will be better,,
