The Quantum project team (QAU token) has announced they will be merging with Tokens.net.
You can read the official statement here.
After careful consideration, GateHub has decided not to support the coin swap and will be delisting QAU.
QAU trading and withdrawals will be available until September 10th, 2018 12:00 UTC. Any remaining QAU issued by GateHub Fifth will be frozen on the XRP Ledger at the same time.
When the withdrawal period ends on September 10th, 2018, GateHub Fifth issued QAU will no longer be redeemable under any circumstances.
Please withdraw QAU to your own ERC-20 wallet before September 10th, 2018.
DO NOT withdraw directly from your GateHub XRP Ledger wallet to the coin-swap address.
UPDATE: Leftover GateHub issued QAU on user's XRP Ledger wallets
The GateHub Fifth issued QAU global freeze on the XRP Ledger has been successfully completed (What is a global freeze?)
GateHub Fifth issued QAU are not redeemable under any circumstance.
In order to dispose of any leftover QAU balances and disable the QAU trust line in your wallet to free up the XRP reserve ( 5 XRP), you can send them back to the issuing address (r3ttJ41YnMrKiLqGUXJpQE8urqyMGjC8vE) via Send payment.
Any leftover QAU balances on Hosted wallets will be removed by GateHub.
