Don't forget, that us, the Gox customers who have fiat/bitcoins on record (right now as debt) will gladly login to our new accounts where we can see our debts and resume trading.
When we resume trading, they will gain commissions.
If they allow BTC withdrawals, limited at first, but allow it - then people will report successful btc withdrawals, others will report successful fiat withdrawal, there will be more transparency in the way the company works and at first, the prices will be lower than the other exchanges. But with time, people will realize it is working in terms of withdraw and trade.. therefore people will want to put more fiat in this "new" exchange to gain some arbitrage opportunity and/or buy cheap for the long run. Therefore new money will find itself landing on the new exchange.
They don't have enough money to allow withdrawals.
If they reopened, there would be a massive flood of withdrawal requests as everyone tried to be the lucky one who actually got paid, and then there would be no money left at all.
Only an idiot would send more money to an exchange which has openly admitted that they don't actually have any money.
What is the good of buying cheap BTC if they don't actually have any BTC to sell you?
You should imagine the situation and see exactly how it folds.
Say they limit the withdrawal to 10BTC/DAY with 50 limit per month...
Then those who have 500 BTC will take 10 months to withdraw... what about those with 5,000 BTC? 100 months... in the current rate.
So yes, manye PEOPLE will withdraw, but not many COINS will be withdrawn,
So they dont need that many BTC to allow withdrawals, furthermore, they can limit BTC withdraw to only verified accounts.
Now, at that point where people withdraw successfuly, both fiat and BTC, others will want to put money in there, maybe small amounts, but they will want to put it there because they could easily arbitrage or just buy cheap and withdraw to an outside wallet.
Therefore, this will resume operations.
