lol, there are a lot of alts that's for sure. I figure some dev is going to "crack the code" so to speak and create the next contender. I hold balances in Argentum, Bitbar, Bitcoin, Digitalcoin, Elacoin, Feathercoin, Flashcoin (Which I regret) Litecoin, Namecoin, Stablecoin and Worldcoin. I am playing the odds that something will be worth it later.
If not, I have learned a ton so far regarding gpus and hashing, that has to be worth something as well.
I'm with krusin; trying to get out of newbie hell, and the fact that I have been dabbling in buying / trading / mining a variety of altcoins as well. I've been trying to hedge my bets by diversifying, with a weighted focus on those that seem more stable or likely.
So far I've bought / traded / mined:
BTC (obviously)
NMC (merged mining after all)
LTC (people call it the silver of digital currency)
FTC (It has had a pretty good run so far)
CNC (because the Chinese run half the world anyway)
WDC (because, well why not)
Bitbar (another well why not)
I don't have any stocks of Argentum, have to look at that one. I'm also thinking of trying to add some high risk bonds to my portfolio if I can get them at the right price. I'm trying to follow a somewhat traditional portfolio risk exposure strategy with low/medium/high risks assets at 60%/30%/10%. Its a little more difficult to figure out risk when it comes altcoins, in fact the the entire crypto-currency thing is a little difficult to gauge. It is probably more realist to say that the risk exposure is medium-low/medium-high/high-high than just low/medium/high, but it all gets normalized anyway.
That's my two cents worth...
