The problem with metaphors is they don't address any specific issues, rather they just amplify fears that understandably exist for all new systems. I suggest metaphor is a poor tool for your argument.
People should do what they want but some additional advice you might offer is to be cautious of people (such as yourself) who are obviously not newbies writing criticisms on one coin page under newbie accounts.
Fair?
The problem you cite with metaphors is your own issue. If you don't understand it you have the choice of jumping on the bandwagon and criticizing or asking for clarification. You choose the bandwagon. Fine.
Zerocoin's development process with regard to anc is deeply flawed and there is very little likelihood any resdulting algo will actually be implemented for any significant length of time.
It starts with a project that was abandoned by some fairly competent people then adds a patch that is ridiculous.
There are scam warning signs all around this project starting with the absurdity of rsa ufo's.
It's almost funny how stupid people can be. Zerocoin is a scam. It may have started with good intentions but anyone who has looked through it knows what is going on. Make some money on the pump if you like. No doubt someone has been making money placing trades based on news about zerocoin.
YES,Bitcoin is a scam,too.and Gavin Andresen who said zerocoin can join bitcoin protocol smoothly is a liar obviously.
