Hello. The article is really useful.
However, I suggest to nobodo checking what he would have won. Just invest now.
There is a chinese proverb: the best time to plant a tree was 20 years ago, the second best time is now.
So, dont look at the past, invest now. Think for the future, because it is ahead of us. Selling before, might have been a good deal for that times, but you couldnt know. So just dont blame yourself if not being millionare. Just become.
Cheers, @duhov!
