The Poloniex's Clam client seems to be in some troubles. When I deposited the clams it took 4-6 hours to get credited few days ago.
The withdrawal today ended up with Complete: Error. And the coins were not credited back to the balance. Contacted support.
Anyway, the margin lending is really high there.
Which is why we created
FreeBitcoins.com/Swap. Fast as fuck every time.
Poloniex support is MUCH better atm, but it'd just be great if their site worked for CLAMS. The know how to fix it.
