To play Devil's advocate - there may be a possibility not yet considered. It is conceivable that they may not be trying to raise capital, as per their statement on the BTbiz site mentions:
"Bitcoin Trader was created by a group of Bitcoin geeks, with the vision to offer ordinary people the opportunity to earn a substantial and sustainable passive income."
It may be possible, and I hope it is, that they are simply sharing profit and not trying to raise funds for something else. They could simply be nice guys, who found a way to make some money, and are happy to share the wealth to whomever puts a little faith in their plan.
Again, just playing Devil's advocate - not being naive. I have money invested with them and stand to lose if it's a scam.
That sounds so nice it must be to good to be true? Free software available everywhere,popular bands giving their new albums away on the net,capitalism's biggest nightmare is coming true. Ever think what the effect would be if Crypto Currency ever took complete hold of the world economy? If you know any Crypto Anarchists,ask them what the best way would be to get everyone into Bitcoin or any other Crypto. The peer to peer civilization is at hand(This is my own opinion and does not necessarily reflect the company or any of it's employees,etc etc etc,so,my thoughts on this one,not BT Official)
