I use 5 exchanges and don't have any issues with them so never have all the coins in one place.
Not really a meaningful statement, there is lots of exchanges but no one that has the liquidity and coin slate of Cryptsy. Some of the most profitable coins are only on Cryptsy, or have a market that actually has buyers and sellers there. The present problem there in trying to get BTC out could be cause of the problems here and elsewhere, who knows, the operator of this pool should be making a statement as to what is causing the delay with BTC exchange for them. I would like to resume mining here, but not until I know the work I am doing will be paid out, otherwise it is completely pointless.
This is not really much more meaningful comments about Cryptsy. keep in mind, that because you can't withdraw from the major coins at Cryptsy, users are buying altcoins at inflated prices, further inflating the price, giving the them the illusion they are more profitable. Also consider why they removed the "trading" fee. This was an attempt to fool a lot of automatic trading scripts, to again think that the coins they have listed are "profitable" since there was no deduction of fee from your net BTC. What they've created is a funnel of altcoins into their system, when they have no means to pay them back out in BTC. Their withdraw fee's are a whole other scam and discussion, which is where they're really raking in their $.
What's important is, I've yet to encounter any other exchange with such problems as Cryptsy.
The removal of trading fees and the introduction of withdrawal fees is not behind Cryptsy's problem. It does encourage a highly liquid high frequency trading environment which is what is needed. Some of the altcoin spreads are ridiculous. The withdrawal fee is not so much of a $ scam if a trader has made many small profit free trades to cover it. Neither is the altcoin 'funnel' a problem. Crypto is not a fractional reserve currency system. There should always be the exact amount of BTC in the system to cover withdrawals unless it has been stolen or misappropriated. The official word is that it is an ongoing system problem. People should have learn't after Mt Gox that an exchange should not be used as a wallet.
Back on topic about this mining pool, is it running on auto pilot or is the owner in a damned if you do, damned if you don't situation about making a statement about the ongoing unexchanged coins issue?
