	didn't you bother to make a summary of the scammers' project? 

	http://www.hashcash.com/faq.html


	"Isn't HashCash centralized, and isn't that bad?

	HashCash is polycentric, rather than centralized. "

	Translation : yes hashcash is just a centralized bank and so
	it is shit.


	"A HashCash vault is a "trusted third party". Isn't that bad?

	A healthy market is full of "trusted third parties. Bla bla bla"

	Translation : yes hashcash is just a centralized bank and so
	it is shit. 


	You're welcome.
