This really smells like a P&D.
You can register as many accounts as you have e-mail adresses.
But still they claim:
purchases are limited to no more than 5 million NeuCoin tokens per registered buyer
So one user can easily "buy" more than 5 million Neucoins for pumping.
And at the end of the day, they may or may not disclose an address where the BTCs are transferred to. Take a closer look at the wording:
"all purchase amounts will be transferred to a publicly visible multisig address."
Well, every address is publicly visible in the Blockchain. But they don't write if they will tell which address it is...
But on the other hand: greed eats brain. So it is well possible that some ppl will really invest some Satoshis.
