I've been holding BTC/LTC/NMC for what feels like forever. I've just started buying other alt coins just to throw some money around because its been getting a tad boring as of late.
I've purchased Quark which has been doing real well for me. I bought some Alphacoins..lol.. not doing so good there. I bought into DVC devcoin because I like the story behind it. I like the fact that open source developers from all around the world can count on making fair money for doing there job, unlike these days where they work for free and only when they can type of thing.
Bought some nibble, same shit as alphacoins, but I do like the name. Phoenix coins, also nothing going on there.
I got worldcoin and zetacoin which I am pleased with both, not making too much money but holding strong.
So.. I think everyone should get into altcoins to some degree. you never know which one may pop but I'll tell you this, SOME WILL POP.. btc and ltc will not be the only two who succeed. I promise you that!
I'm especially thinking about buying at least 1 dollar worth of coins that cost as little as 3 cents etc...- Imagine how many wallets I'll have lol. If bitcoins really take off beyond this point, I'm hoping that people who're getting into the game late rush toward those coins, tightening up their demand.
