If somebody solves a puzzle and has the private key, the authentic and safe way to prove it is signing a message with that private key. If somebody tries to prove it with pictures and videos, it is 100% fake.

The SEKO deposit/withdraw disappeared from Cryptobridge? What is going here? When will be this fixed?
Is there any other exchange supporting this coin (with deposit/withdraw)?

I'm in the same situation. I contacted them two times in in email (admin@dwarfpool.com), but no answer and still no solution.
Where can we reach their "Excellent Support 24/7 in english, pyccкий, deutsch" ? It seems there is no support at all.

Dear Bittrex Team,

Can you somebody some my issue? Cause your BTG wallet is offline without a valid reason, I can not access my deposited coins, which were still under confirmation when the wallet went offline (A month ago!)

"Wallet Offline - Awaiting feedback from developers"

Any update on this? Who can solve this issue, who should we contact at Bittrex? Who are the responsibles? Who are those "developers"? We want anwers as we still can not access our coins!

Still the same on Bittrex:
"Notice: Wallet Offline - Awaiting feedback from developers"

Can somebody do something? Who are those developers?

Forget Bittrex immediatelly! Scam, fraud, liars, thieves!
They put offline Bitcoin Gold wallet more than 2 weeks ago, because there was some issue with the wallet, causing tons of coins inaccessible. And they have no willingness to solve the issue somehow, they are just simply closing the support tickets. They are lying that they are waiting the for the solution from the developers. However, other exhanges fixed the issue in days. Meanwhile, their BTG/BTC exchange is still running, just for price manipulation purposes.

Dear All,
Beware of VIABTC. It seems to be an organised scam, fraud, crime etc.!
At some times they just simly don't pay the PPS reward and according to their explanation they think their clients are stupid.
Normally, a PPS payout means that the pool pays you for every share, regardless of pool luck and regardless of mining time. But at VIABTC, sometimes not. Look at this conversation:

Me:
"Dear Support

I mined on your BTC pool in PPS+ mode with my subaccount *** (Workers *** and *** ) around 06/06/2018 20:20 - 20.45 UTC, with an average hashrate of 22PH/s, (peak hashrate around 28,6PH/s).
However, I didn't receive the PPS+ reward. Please fix it.
Proof attached (hashrate screen)

Thanks"

VIABTC answer:
"Thanks for contacting ViaBTC support.
The profit of PPS+ mode consists of two parts: PPS profit and PPLNS profit.
Due to the PPS profit is allocated every 1 hours, but you've mined on BTC pool only 20 minutes. So there was no PPS profit.
Please check your PPLNS profit in your wallet.

Kind regards"

So I was not rewarded because I didn't mined for an hour, only for 20 minutes.
It is not first time, I have proof that it happened minimum two times, but possibly more times also.

I'm suspicious (but I don't have exact proof) that they also stole a Bitcoin cash solo mining reward (12,5 BCHs) when I was mining on their pool in solo mode.
My ASIC showed  that it has been found a block. I know that the statistics of the ASICs are not reliable but there is a little chance that at same time the pool also finds a block.
And of course, they explained, that somebody else was the block founder.

The other scam, which happened some months ago is that they only paid around half of the PPS reward for BCH mining.

So my advice is to avoid this pool. Avoid it far away.

BTG wallet on Binance is up.
Bittrex just simply don't want to bring the BTG wallet up, as tons of BTG coins were stuck. They are just simply closing the related support tickets and pointing to "developers". However, to be able to manipulate BTG price and collect exchange fees, they BTG-BTC exchange on Bittrex is up. But no deposit/withdraw, just "insider" trading.

Is there an accidental fork on the monkey network?
The blockchain is different on those 2 block explorers:
https://www.coinexplorer.net/MONK

http://chain.monkey.vision/

Still the same. And the support is not doing anything, except closing all related tickets without any meaningful work.
If this is not solved in the next coming days, we are going to start serious legal actions (debt collection, company liquidation etc.) against Bittrex Inc.
Until that, we will derate Bittrex on all crypto and scam-review sites.

Bittrex's BTG wallet is still offline, and they have no willingness to solve it, they are simply forcibly closing related support tickets without any meaningful work. 

SCAM - unethical business - not customer friendly - AVOID THEM!

They put BTG wallet in maintenance 11 days ago, making tons of deposits inaccessible. They are lying that they need feedback from developers. (Meantime, other exchanges fixed BTG issues in days.)
And Bittrex's support is unable to help, actually they have no willingness to solve the issue.
(And they are forcibly closing the support tickets without any meaningful work. )

They are forcibly closing my tickets without any meaningful work, which is a very questionable behaviour.

IT IS A SCAM!
They put BTG wallet in maintenance 10 days ago, making tons of deposits inaccessible. They are lying that they need feedback from developers. (Meantime, other exchanges fixed BTG issues in days.)
And Bittrex's support is unable to help, actually they have no willingness to solve the issue.

Bittrex's BTG wallet is still offline. Now the official reason is: "Wallet Offline - Awaiting feedback from developers"
Dear developers! Do you know anything?

As far as I know, the attack is over. However, Bittrex (and perhaps some other exhances also) is holding back tons of BTG coins, because they wallet is "automated maintenance" since Saturday. (However, the trade is on.) What kind of manipulation is this?
And they are unable to recover those coins, which are stuck. 

What the heck is going on Bittrex? The BTG wallett is in "automated maintenance" since Saturday? They are sitting on my and other people's coins.
