OK, but it says absolutely nothing about actual chance to come up with something that is able to consistently predict line movement. My estimate is that this chance, although exists, is absolutely tiny, and this correlates perfectly with %% of players who are actual long term winners in this game which is also absolutely tiny.

It is also true that if you can do astrophysical calculations in your head you can make a lot of money,
if you can create ipad you can make a lot of money, if you can sell snow to Eskimo you can make a lot of money, if you can run 100m faster than 10sec you can make a lot of money and yet we don't really see millions around the world trying themselves out in hopes of fast fortunes.
Apparently, there is still enough common sense around for people to realize that although money is there alright, task itself is way over their heads and the fact that someone out there can do it and they can't does not seam to matter to anyone.
But when it comes to BTCL, playing poker or trading stocks every one seems to think that he is not only as good as the next guy but better and therefore a big pile of gold just one winning pattern away. All is needed is past data, excel and a few statistical tricks.
