Greatest ever?? Suppose it depends upon which scoreboard you look at. Investment wise, I use the one that says who's got the most $$$$'s is the greatest. Doesn't matter one bit how he got it, the fact is, he has got it. On that score, he's way out in front. Other than the elite traders of course.
Jeez, 2 prices already. 1 of the prices is real. The other is unreal. Buy the unreal one, when its unreal. That don't take much tech. What it takes is slow money, that's a rare commodity.
worlds greatest investor does not use fancy tools Nay. He uses the most advanced and fancy tool: The computer between his ears.
