Yeah that sucks the big one. It's hard to know isn't it, especially when the big pump is on and all the noise starts. Very easy to get caught up in it all. You just don't want to be the one left holding when the music stops so more often than not it's safest to bail when your in front. I got one bag out of it, but missed quite a few more! got it right but also got it very wrong
I guess if it was that easy, everyone would be rich wouldn't they... anyways, it's one of those things; sorting wheat from chaff will always be hard when speculation is involved.
