People are buying them, because they are using them to buy things.
When the price falls, they get more coins... Why would they NOT buy them? If you were told you could get 3000 burgers today, or wait until tomorrow and get 4000... would you NOT buy the 4000 if you wanted burgers?
Why, because this coin is marketed, unlike many of the scrypt-coins which are just diversions to distract the idiot pump-n-dumping morons who normally cause trouble on the BTC chain. They trade expired labor for expired labor... lol. (Talking about the unmarketed coins. Not the marketed scrypt-coins.)
Marketed scrypt-coins (No perticular order.)
- WorldCoin
- LiteCoin
- DigitalCoin
- BBQ-Coin
- MinCoin
- LuckyCoin
- NovaCoin
- BitBar
- Nibble
- MemeCoin (Yes it has a market. Meme's.)
- SexCoin (Yes, it is still alive and being sold/purchased off-market, to reduce the pump-n-dumper moron damage.)
Unmarketed
- FeatherCoin (Was intended as a CPU alternative to bitcoins, now raided by all the GPU's. Hit the hardest by the pump-n-dumper, since it had one of the lowest diffs.)
- FastCoin (An ADD coin, for the impatient to mine.)
- CHNcoin (China-coin for Yuan? Might be marketed in china. Yuan to USD is dropping fast, so not worth any US investment, unless you get it when it peaks low.)
- Phenix (Misspelled Phoenix? lol. They live there, and they still misspelled it! Obviously a failed attempt to be creative.)
- HyperCoin (The other ADD coin, for the impatient to mine.)
- Franko (Good old Franko... You can buy his old socks and underwear with the coins, guaranteed... and also possibly a few ounces of Oregano.)
- PowerCoin (Yes, we are all making the power-company lots of money, this coin is just doing it faster than others.)
- ElaCoin (OMG Ellen has a coin! NVM it's Ela, the Enduser-License-Agreement that drains your wallet.)
- AmericanCoin (Made in china. Nuff said. CHNcoin trying to capture both markets. It's as american as... Pizza, as hot-dogs, as Indians... Oh wait, those are all foreign things from other countries too.)
Any other not listed... I would assume has zero-market also... Or is dead in the water.
