Popular US-based cryptocurrency exchange released statement regarding the BTG hardfork.

We've stated in the past that the safety of our users' tokens is our chief concern. As such, we have refused to support a forked token unless it had implemented replay protection. We would like to further urge our users to be immensely cautious of any token that expects to be given private keys that control value on another blockchain. This is dangerous and unnecessary, even for an alt like BTG that seeks to distribute tokens using the state of an existing blockchain.

Poloniex Statement

Additionally, Poloniex released reminders that apply to all balance-duplicating alts:

  1. If you wish to be guaranteed tokens distributed according to existing blockchain address balances, you should keep your tokens in addresses for which you control the private keys.
  2. If Poloniex credit accounts with forked tokens, they will do so according to balances at the time of the fork. If you have tokens on loan at the time of any fork related to that token, they are not in your balance, therefore you will not receive any forked tokens for them.
  3. Under no circumstances will we redeem tokens distributed according to the balances of addresses that contain customer funds and keep them for ourselves. Should we redeem them, we would only do so to distribute them to our users.


Poloniex accounts display incorrect amounts, users have problems with account management

Canceled orders on Poloniex do not return money back to the accounts, users report losing control of their accounts due to alerts “spazzing out”

Since yesterday there were reports on Poloniex's unofficial subreddit about platform not returning the funds for canceled orders. All started with one user expressing his displeasure with the fact, and quickly grew to a whole new level with several more complaints added in the span of the day. Poloniex even responded on their official Twitter account that investigation is ongoing into the malfunction.

But there is more. There surfaced a report by a users, whose accounts balance just glitched out and is displaying inaccurate or outright negative amounts. For example, one user reported strange happenings with his margin account. By themselves the positions show correct values, but account as a whole is under 16% margin and is full of alerts. Thankfully, no assets are liquidated even under “Forced Liquidation” alert, but the ability to manipulate anything is lost. Poloniex replied to that issue as well, saying that everything will be corrected in short order.

All of that contributes to a series of problems with Poloniex, which have been amounting already for over a year. Customer service is swamped with tickets and the response times are getting longer. There were complaints about one ticket remaining unanswered for 158 days. And withdrawal times are even stranger. Some users have to wait for a month or more to get access to their own money, despite asking the support service for assistance.
