This is stupid math as it is based on the premise that all market traders are idiots. In fact, increasing fee 1.5x will lower trading volume 10x, finally the system lost more. You can still try if you dont believe in this, but I can tell you it is irreversible, people wont come back when you lower the fee afterwards.
If the BTS price is going down, the reasonable thing to do is to exame the system for what is actually done wrong, even if there were thousands of theories backing it. Not to mention that every CXO should ask himself about this question 10x more, and take your financial lost as your responsibility.
