-> Switch to Litecoins with can't have Asics
Why do people still believe this? If something can be done on a general purpose chip, it can be done on a application specific chip.
Because it will be expensive.
HELLA expensive. You need the fitting RAM on it. If a 7970 at 700kh/s needs around 1.5gb of GDDR5 ram, consider what amount you need to make a 5MH/s Scrypt miner. (The answer is around 64gb GDDR5 ram)
People believe it because that's how it is. The "general purpose chip" is not doing the bulk of the computing, and requires a ton of RAM. If you think someone will make some sort of super-ram for scrypt mining, maybe you can share your thoughts on that, otherwise it's pretty clear ASICs hold little scrypt potential ATM
