Prior to confirmation (which may take many minutes) bitcoin transactions are at risk of double spending. Normally it is not that huge deal for normal bitcoin user.
But this also means a scammer could spend the same amount of bitcoin more than once. When bitcoin will go mainstream it can become huge problem for some bitcoin companies.

Hi, exactly where did you see that, and under what conditions?  More details are needed.

Basically a double spend is when someone tries to spend the same bitcoin(s) twice.  It is nearly impossible to do, and to my knowledge has only been done once (I could be wrong about that).

If you are involved in some sort of transaction then just wait for at least 2 confirmations, that will ensure that there is no double spend.  Sorry I am a little fuzzy on the technicals, but it is extremely unlikely that a double spend has occurred.  However please provide more details because if there is a double spend it needs to be forwarded to the dev team immediately.

sorry i cant provide the transaction id..as i am betting on that site and it is paying me off../
btw thanks for the information.

thank you.

I would transfer the coins to a new addresss and would start using that from now on. If they confirm you know that your coins are good.

they are basically like fake bitcoin, bitcoin that belongs to a different chain and that now are useless

notice how it say "may", probably there is't any double spend, just a warning
