I also believe it is s scam. If its all based on % why have a min buy in. Other trading site's like gdax dont have a min $ buy in. Gdax has a min crypt tranfer number, but that really low. With a hundred $ buy in they can afford to pay out people until they grow the pyramid. Why change bit to bcc? With % crpto moves up every day 1% is like crumbs from the kings table.
