Undercutting

[jomoru]

So at that point I decided to learn from it. I enter into a field of about 4-5 goods and I use a very similar method, I drive out my competition while stocking up, then make profit off the stock, then drive it higher for even more profit. Others begin trying to hop on board and make profit from my efforts there- and then I start the process again, often demolishing them in the process. Not always, just often.

Good for you, i of course get around "attempts to destroy me" by being diversified and not requiring one thing to sell.
