Withdrawal delays=chance of not seeing your hard-won money again
Deposit delays=find a different investment venue for your dirty fiat.
Totally different issues.
It is chance not seeing your money again x2.
And another indicator of liquidity problems.
And that any new money coming will be postponed. And that some will not deposit, as they can miss bottom.
Oh no, missing bottom... Tragedy... Meanwhile, the people setting the price already have their money there.
Answer to your first statement: If you got money there, you can at least buy btc and withdraw them.
To second one: So you think no new people are needed for BTC to succeed? At the end it will be just you trading there.
It's not tragedy, just not very good sign for any new people to invest. Gox is not some super factory producing BTC and $. Simple mass balance can tell you this.
And if you think instant buying of 50 BTC is big news, that should be even bigger.
