I heard that the inside of the C - CEX BTC appeared problem, according to the number of is you actually have a lot of times, but can't extract, so should be extracted to switch to other COINS
don't quite understand what you're saying here
my english is poor.I use the translation
i mean you Deposit 1 BTC ,but 100 BTC shown on the website,can't withdraw btc
so need exchange other COINS
Just listen to other people say so, don't know is true
I've heard the same thing. I heard there was an exploit on ccex and tons of DRK were purchased then withdrawn which is why we're now seeing huge sell walls on Poloniex.
No idea on the legitimacy of that claim but it would make sense based upon what we saw.
This is why you keep very little coin in exchanges.
