There are two techniques commonly used by day traders to increase their profits from market movements. Leverage, or margin trading, means borrowing money on a short-term basis to speculate on the price of bitcoin. The loan is paid back when you exit the position. For example:
The price of bitcoin is $500. You borrow $5,000 to buy 10 bitcoins.
The price of bitcoin rises to $550. You sell your 10 bitcoins for a total of $5,500.
You pay back the loan of $5,000, plus interest (say, $50).
Profit: $450, on a price movement of $50.
Of course, you can also lose a lot of money this way: if the price goes down instead of up, you will lose ten times the price movement. This is what makes margin trading so risky – it is potentially extremely profitable, but can also be very costly.
http://bitcoindaytrading.net/day-trading-information/Investing in Bitcoin is a pretty risky business, so you should only use a relatively small amount of capital that you can afford to lose entirely if things go badly. But these high risks could also come with high rewards.
You can still make money from mining coins, from buying and holding them, or from trading them on the financial markets.

It is possible that the price will drop, an alternate digital currency will overtake it, or it will eventually collapse. The Blockchain technology that Bitcoin is built on is likely to prosper on well after bitcoin as it can be applied to many other problems such as property ownership, drm, escrow, etc.
