1,000 satoshi? You must be kidding. That's even less than the minimum amount per transaction in trading sites. Remember that trading is an investment too and I don't think 1,000 satoshi is a reasonable amount of capital in investment. You can't even get $1 out of your pocket? 1,000 satoshi is just one claim away from faucet sites. 1,000 satoshi wouldn't get you somewhere even if the price of the altcoin you bought goes 100x (which is very unlikely).
No, I am not. One can start trading with 1000 satoshi but you are forgetting one most important thing and that is platform. Trading not always means buying and selling bitcoins on a particular website (that’s the traditional method). Trading has very large scope and that includes trading on open platforms where there are no third party fees, buying with one payment and selling with many platforms. One must be innovative, prompt and capable of taking risks, that’s what trading is all about in my opinion.
I honestly haven't heard of a platform (aside from altcoins) where you are allowed to trade with amounts as low as 1000 satoshi's. Can you name up a platform where you're allowed to trade with amounts that low? Not that I am going to use it, but just to see what their terms are when it comes to executing orders that small.
