I know, that I can always buy cheap and sell high... but I am really confused by all that shorting and borrowing stuff.

I would like to get simple answer/instruction, what should I do, if I believe, that BTS will rise against USD?

Should I borrow then USD using BTS, and then sell USD by buying more BTS?

Could someone could prepare very basic tutorial for newbie traders?

If my understanding is correct, that would be very helpful if such tips would be available in gui... describing few scenarios. Descriptions of Prediction Assets has this kind of tips:

If you believe that the price will be above $40.00 buy and hold. If you beleive the price will be below $40.00 borrow and sell.
