OP stated: If MTGOX supposedly is having liquidity probs --- Why the fuk are they still allowing bitcoin withdrawals? It doesn't matter whether u withdraw bitcoin or USD, if u do either the money is gone from their account. So I call BS on all this speculation they don't have any money left to run their shit.--------------------------------------------------------------------------------------------------------------------------------------------------------------------
Turns out that MTGOX didn't have either BTC or money.
My response:
If you do either, the money ISN'T gone from their account. If you transfer a BTC out, then yes, the BTC is no longer on the MTGOX exchange. But, if you sell a BTC and then have funds in your account (or so it says on your MTGOX page) those "funds" aren't leaving MTGOX's account. Prove to yourself that those funds actually exist.
The notion that a lack of liquidity would prevent MTGOX from permitting BTC withdrawals is flawed. The purchase of BTC's on MTGOX right now is being performed based on funds that are simply listed on your account. It's almost like a demo account with fake money, but the BTC's are real. If you can't get your funds out, how do you know that it actually exists?
Say MTGOX only has 2 customers (A and B). Customer A has 100 BTC's and B has enough USD in their MTGOX account to purchase all of those BTC's. Customer B with USD in GOX can't withdraw, so B buys all of Customer A 's BTC and transfers them to another exchange where B can sell those BTC's and make a withdrawal without an issue.
Customer A now has USD in their GOX account, however it's USD that they can't withdraw and there are no other customers to purchase BTC's from, so A is stuck with his/her USD in GOX and no way to get it out --- No one to buy BTC's from and no way to get the USD out because MTGOX isn't processing the withdrawal. Now the million dollar question is this: DO THE FUNDS NOW IN CUSTOMER A's ACCOUNT ACTUALLY EXIST? It say's that they have it on their MTGOX account, but does it really exist?
It's not like MTGOX has an independent 3rd party that can audit them to say that they indeed have everyone's funds and are solvent. All we are left with is an account page that says that you have $xxxxxx.00
You can purchase BTC's with those funds listed there, because for the moment, everyone believes that those funds are real. But can you all withdraw your funds right now?
What's working in the MTGOX's favor right now is the fact that they obviously don't have just 2 customers. Additionally, customers are depositing funds. What's saving them from a collapse is that the simplified scenario above is being prevented by the thousands of MTGOX customers who aren't heading for the door at once. BUT, if something were to trigger a panic, we'd see the price of BTC's on MTGOX shoot up and those willing to take a lose by purchasing BTC's at panic prices will be able to get their funds out through the transfer of BTC's and those left holding USD will be out of luck. Those left holding USD will have their USD delineated on their MTGOX page, but are those funds really there? Since there wouldn't be anyone to "buy" BTC's from (because they left with the BTC's that you sold them), you could put in a request to withdraw those funds, but when that request doesn't get fulfilled (like the stories that we keep reading on this forum), is your money really in your account?
You can "buy" BTC's with the funds listed on your MTGOX account because everyone believes that those funds really exist and accept them (electronically), even if they can't withdraw those funds. You can then transfer those BTC's out and it has nothing to do with the liquidity of MTGOX. The acquisition of BTC's and the transfer of BTC's is solely based on the belief that the funds listed on your MTGOX account are real.
If you can prove that those funds in your account actually exist, then your belief that MTGOX is solvent is founded.
However, the fact that BTC's can be transferred out of MTGOX does not prove that MTGOX is solvent.
