I suggest you to know the market's tendency first!
Of course you should study and do your homework and see it goes. Although there's a lot of irrational buyers last December who got burned during the crash, sold and lost money. But I guess, there's nothing to worry if you are a long term holder. The market is very volatile to begin with, if you are not patience to wait for it to recover then I guess you should stay away. This is not a quick rich scheme so you should be very careful in investing because everyday the price changes and it depends on you if you see the market not going in your favor. Are you going to hold or sell?
