I have heard a Chinese exchange has just made some mess in this sense, do you have any names of exchanges Which have been proven to adopt this habit?

I recently heard about this people on the forum sending out merits to people undeserving to it. It makes me wonder how they do it and this is getting unfair for people who works hard to gain merit..this is saddening. If merit system has not yet arrive i could have been a member now if we base it to the number of postage. For me MERIT SYSTEM just fave the way to cheating here in the forum. I wish we go back to the old system of basing the ranking on the number of posts this way we can be assure that people deserve their ranks.

If you buy Bitcoin in exchanger, exchanger send you only when you withdraw.
When people start withdraw Bitcoin will happen MtGox2

So you will lost all you money in next MtGox scam.

ALL Bitcoin "hacks" it just way to avoid judicial responsibility.

I will say it again. Inside job. None of those fools around here got brains for more than simple theft.

Otherwise they would have found a well paid honest job.

That coming with the ability to choose different so no excuses will be needed on the last day.

If the bitcoin drops to $ 3000. That can happen. At that time you can happen on a large floor, the other floor will close, the best way is to withdraw all coin off the floor. That may be true

Yes, it is not advisable to keep the coins at the exchanges. I only keep those coins in exchange on which i have to trade. Once trading is done, i move my all coins back to the wallet. It do cost me some tx fee for withdrawing from exchange but it save my money in case something wrong happen with the exchange.
