)) It costs almost nothing You don't seem to get it: Solidcoin®∞ unstoppable. Imagine a hippo in the wild, nurturing its offspring as the tiny hippo suckles the teet of the mother hippo. Now imagine a poacher appears! The hippo becomes angry! So angry, the hippo grows bigger, muscular, green, and its purple shorts rip right off! So there they face off, the poacher and the hulk hippo with the aforementioned baby hippo still attatched to the teet, suckling it's hippo nutrition right out of the angry hulk hippo! So much that the mother hippo shrivels right up, the baby hippo goes off to med-school, and the poacher goes home to spend time with his family.
That's what Solidcoin®∞ is.
