Re: Building the next generation FAST CRYPTO CURRENCY MINING MACHINE
Not sure where you are from but reading doesn't hurt 
For low-value transactions no waiting is necessary.
Experience. "Bitcoin transactions are instant - the confirmations aren't. It usually takes less than an hour for the first confirmation." There is no such thing as a "low value" transaction... Milk is NOT free and if buyers use bitcoin you are asking the merchant to risk being robbed... else hold his customer for an hour. For low-value transactions no waiting is necessary.Are you sure it's worth it?
It's CERTAINLY worth having a discussion, yes. Particularly about this:
I like scrypt but it is still relatively new and I wouldn't be surprised if someone found a flaw
only those with the best economies of scale will remain in business with profit margins decreasing.
As a "rich American" I find this troubling. People who cannot (or will not) afford ASICs will STILL want to mine. Crypto Currency is about MASS adoption. If only Vlad is mining then everyone else will migrate elsewhere. So Vlad mines Bitcoin and the rest of the world moves to some other currency they *think* cannot be beaten with an ASIC.
