All clams sent to my wallet never show up, and the mining part is super opaque/non transparent and has not paid out either. Does this mean all the clams I bought on poloniex are vanished in transaction?
Withdrawals from poloniex.com disappear... whelp, that sucked.
If you had a withdrawal from Poloniex disappear you should certainly contact support at Poloniex!
I believe this is the link:
