That's a serious and bold accusation. What evidence do you have to support your claim that the second largest investment bank in the world is involved in a "pump and dump" scheme? Goldman Sachs has been in business since 1869. You don't stay in business 156 years running "pump and dump" schemes on the public.I have do doubt that GS is buying up bitcom with both hands. But make no mistake, Goldman is not buying to hold. They will hold until just before the bottom falls out of the retail market. They will be selling with both hands while retail investors are wondering what’s happening. It’s called a pump and dump
