It's impossible to flip large $$ volumes without hurting yourself.
Take JBZY right now. A long could easily have accumulated 10 to 100 million shares at .0001 -.001 range. There's NO WAY he could flip those at current prices. That's why most who like to trade will hold a core and only flip a few, but the BIG money comes from holding a large core of the RIGHT stock.
Waiting patiently, yet the anticipation is getting pretty darn thick recently...
