How do traders make money while trading bitcoin in localbitcoin.com ?

Buying at cheap and selling at high - simple and fast. Or they buy at BTC mining pools and then sale at localbitcoin - it is even more smart.

I am new to bitcoin and loving it. I have an account with localbitcoin and i see, there are so many people buying and selling btc. I am wondering, how do they make money while trading using localbitcoin ? And can it be a good business ? 

you can earn in trading at localbitcoins as long as you have patience in waiting for the right timing in selling your btc.  same as in buying btc you have to be good in handling your transactions.  be up to date always or updated to the fastest time ever.  most of the customers want their transaction/s done right away.  just manage things nicely and it will be really wonderful to be in the bitcoin business..
