Altcoins are going quite up in prices the last time, just have a look on litecoin, NMC, PPC, and so on.

Think its now the time to invest in some smaler altcoins, like worldcoin. If the other coins rise in value many people might convert their capital into cheaper ones to speculate that they will also raise in price. To be an early adopter might be more profitable than to invest in coins wich are allready well established.
