Can't read the article but how did they cash out? Use the mobilecoin as collateral to buy btc and transfer the btc out? Example: take $6 in mobile coin and pump to 60, then borrow $30 using the $60 as collateral and buy $30 worth of bitcoin and finally transfer that bitcoin out. You then have a 5x return ignoring cost to pump?
