Perhaps diversify more widely for protection from flash crashes and unforseen growths of other assets.

This is a good time to buy crypto as the last price correction has already hit and now we are seeing sideway movement so the chances of you "buying at the top" is unlikely.

Litecoin has a lot of potential and has finally secured it's own independent payment processor(Something we've desperately needed for a long time now),
along with exchanges promising to pick it up soon(Coinbase, BTChina primarily) ... and technically MtGox - but F#$ them.

Would recommend against NXT. Most of the promised features have not made it in and the coins are too centralized in a mere 40 people who all know each other before it's launch.(As in 90% of the coins. Even worse than Bitcoin had during it's launch. There's no excuse for it now.)

Emunies on the other hand already has all the features, plus more, and as a Beta tester I can say it will be released fully functional. The coins are spread out widely amongst
the user base. The Dev is also a well known Google Engineer who has shown himself to be competent for the position. But that's just my biased opinion.

Protoshares are interesting as implanting some unique ideas not done in any other ult. This is a great time to buy as the value is down due to Angelshares absorbing a lot of the new money but that will change shortly.

CryptogenicBullion has not yet delivered their promise but is developing a blockchain to act as a database storage / function as a legal contract framework. Another unique idea not tried by anyone else. The value is very low as the MADEsparq Project is still in development but if the Dev releases it properly I see a game changing digital currency in the near future.

You should also consider some precious metals like Gold and Silver. It is generally agreed that the market has finally bottomed out and the slightest economic tremble from the US (such as when it is revealed that QE won't/can't be stopped) the value of digital currencies and precious metals will be sent into the stratosphere. Especially Silver.

It also gives you something shiny to play with when you are checking currency price charts and responding to the trolls that "bitcoin has no value".
