Any reason you needed to post this link to a picture of a bar of gold on 3 different threads? I guess the same reason you needed to post a link to a Cab Callaway video in this thread.
People always say this when the market environment undergoes change. I'm sure the SOES bandits were moaning like hell when that edge disappeared - but there were other edges and if new traders had listened to the moaning then they would have given up right from the start. One method of trading may have lost some of its profitability, but that doesn't mean it's a bad time to start for new traders.
I think for most traders, volatility is the key to profitability. If there is little vol, there is little opportunity to profit from changes in price. The volatility is dying out there. It feels like 2005 out there. Like watching paint dry. It is a bad time to start for traders. 2007 was a great time.
You could also argue the contrary. Since there was much more volatility in 2007 it was therefore easier for less experienced traders to get blown out. Currently it may be more challenging to trade with less volatility for experienced traders, but newer traders might preserve their capital long enough to learn this business. Really you could argue either way which environment is better. The fact remains, you have to start sometime. You can't learn to swim if you don't jump in the water.
