An excerpt from their website states:
"We have recently completed a major upgrade to our customer identification and verification systems. As a result, we will soon require legacy accounts to become verified through the latest version of our verification portal. The exact date for this deadline will be announced in Q1 2018. While you will be given advance notice before this requirement goes into effect, we encourage you to verify your legacy account now to avoid any potential interruptions in your ability to trade on the platform."
The following rules will apply to unverified accounts once the policy takes effect:
-Trading and lending will be disabled
-Open orders will be closed
-Loans will have auto-renew switched off
-Margin positions will be given an 8-week wind-down period where they can only be diminished or closed. After the 8-week wind-down period, they will be closed
-Deposit addresses will be revoked. Any deposits sent to a revoked address will not be recoverable until the account is fully verified
-Withdrawals will remain enabled at the daily withdrawal limits prior to the deadline
I guess we're just spreading our vital information to more and more websites where hackers can steal our identity. Totally risk-free.
