I haven't been in any trading schemes but as far as I know, what you've deposited is a bit on the low side. The best starting money would be in the range of 1-0.1btc to get the best results. By the way, since you're doing your business in Poloniex then maybe you should buy Gunbot once you've earned enough bitcoins. I'm not advertising his bot but most buyers didn't regret buying it.
