Do you think they got hacked and had their coins stolen? And now they're delaying deposits and withdrawals to cover it up? Could it be my ETH were used to finally process another user's delayed withdrawal request?
it's anybody's guess at this point. their recent change of terms and cryptsy-like behavior suggest this is possible.
My understanding, at least what the staff said many times in the trollbox, is that after getting hacked years ago they went above and beyond with their security measures to not let that happen again. They said the vast majority of coins where in cold storage and vs using a hot wallet when the hack happened and so on. Though it's possible, no one can really know. Using an exchange is always a risk regardless.
i would certainly hope that most of their crypto is in cold storage. but for one thing, talk is cheap, and for another thing, that doesn't cover all security risks. for example, who has access to the cold storage? nothing is 100% fail-safe.
yeah, using any exchange is a risk....some bigger than others. the unregulated fiat exchanges like bitfinex and kraken are at additional risk because they are unlicensed MSBs. so are poloniex and bittrex, but at least they don't process fiat money. among the exchanges mentioned here, poloniex definitely seems particularly risky given the circumstances. their new terms said something like "no class actions in case of loss" (i.e. like gox) and "you can only sue us from massachusetts, USA in case of loss".... that doesn't sound encouraging to me.
