Yes, it is time to panic!
The stock markets are going to fall, then collapse, and they will never get up again. The corruption is so deep that only a collapse can clean it up. DTCC failure to delivers... should never happen, why isn't the stock market shut down and a complete audit happening? Well, the reason is, it would expose the rigging, and worse it would expose that most stocks are sold 4 or 5 times.
So, the stock markets are just a bunch of people betting on the movements of numbers without any basis or backing. At least with the tulip mania, you had a tulip bulb.
