I have an advise for those of you who want to withdraw WRC from HitBTC.

This is the main account where all their Ether Tokens are stored: https://etherscan.io/tokentxns?a=0xf07232bc85d995c32c1edf1c985c84a8b7b0ded7&p=1

For each token they have various other Ether Accounts, from where withdrawals are sent.
Their Worldcore account looks like that: https://etherscan.io/address/0x6e3a812e4b19d8dd8c25a3e2e54a127b75ec7033#tokentxns

Unfortunately they let those account become empty, and they leave it in an empty state for days before transfering more funds to those accounts.

So my advise is to check their Worldcore Token account, if there are enough funds on it:
