It is potentially possible to make some money trading $1 back and forth, but you'd need an exchange with extremely low transaction fees and you'd have to be watching the market a fair amount, depending on how badly you want to keep your $1.

As for your profit, you might make an additional dollar every two month or so, depending on if you do day trading or hold over time, and whether or not you're doing a lot of trading. I'd expect that roughly every dollar Bitcoin moves will generate roughly $0.001 or less, I'm not doing the math right now, so you have to keep that in mind.

No its not posible bcoz in trading had transaction fees 1$ is very low amount.

yes it is possible to trade with it but your profit will be negligible. you should trade with larger amounts to get better results as everyone suggested above.

On most sites the minimum trade is about 0.01BTC which is about $7 at the moment.

You can trade it back and forth, reinvesting your profits, and eventually compound interest will come to your rescue, but it could take you a decade or more to make much money. You are better off starting with a larger stake.

Yes its possible ,and you can make your btc grow with trading ,if you some skills when it comes into trading.
It all statrs in a small things. . So dont be afraid to enter into trading

It is possible but you cannot do it in exchange sites because they have minimum. You can do this by making a thread in currency exchange if i am not mistaken. Goodluck

You can try trading with $1 or less at yobit  but you will not be able to get profits as most of the profits will be detected in trading fee. Its better is you start trading with atleast $10 or more. The more you invest in trading the better is the for you to get better profits. For this reason i always trade with $50 or more and get reasonable profits.

I do not think it will be possible to make any profit with small amounts like 1$. some sites does not allow less than .01 btc to trade. it may work in trading btc with altcoins but you wont get any high profit with this small investment

Yes it is possible to trade at small amounts but don't expect huge profit from it.  Let us say you invested 1 USD, don't expect to have 1000 USD profit from it in a short period of time. Unless you were the early people who bought BTC at less than 1 USD ea.
I beg to disagree that you will never made a profit with 1 USD, even your own statement contradict what you have said.
 
huge amount of dollar or tiny amount of cent gain is still a profit.  

I suppose that you can use small amounts if you are a newbie and want to learn more about trading without risking much but don't expect to make big profit you need to invest much more than 1$ to see some good results.
