Reputation of Poloniex are not very great in the recent years and also they have warning at their deposit page of don't send wrong coins to this address or it will result into permanent loss so the chances for you is less.

I don't realy know if a USDT private key is identical to a BTC private key... I think it will be difficult for you to recover your BTC. I had made a mistake a little like this, but with BCH at Bittrex. I sent BCH to a BTC address. They didn't do anything at that time. It was just after the release of BCH. They only say that they can do something if it was more than 5000 USD. And i suppose they take some fees for the extra work.

Then when you have messaged them? okay I thought that you made the transaction recently because Binance halt transactions lately so that makes sense. Moving on.

They will help you as long as you give them the needed details and explain to them properly on what really happened and your situation. For now, we can't do something about it but to be patient and wait for their response.

This was a warning sign but you ignored it. Even if your love for Bittrex emotionally blinded you to reasoning, you could have bought the first IEO (VBK) when the price dropped abysmally after the IEO than buy the new IEO. Well, for me, even though I believe IEOs are way better than  ICOs, I still know all isn't well yet with IEOs. I would rather buy an IEO from Binance only if I were to buy at all because it's the most secured exchange at the moment.


Quitters don't win and winners don't quit.

I am not sure anyone would want to throw their winning strategy at you like that without you putting in the works. Work on your mindset first.


Thanks you sir , work hard and play hard .

Investing is always accompanied by risk, what is saddened from your experienced is the exchange who you entrust your money, thinking that Bittrex will be able to equal or excel against Binance in terms of this IEO's offers, having a big accomplished business compared to those small exchange around this industry, but it happened the initial offering did not provide good outcome.

Unexpected  and yet life must go on, if you think that it's not your luck to keep proceeding with IEO's then go and move on dealing with trading,
existing coins that have a good future.

I do believe that such terrible situation that you experienced in Bittrex has been happening to others also, even in other exchanges like Binance.
There are projects in Binance that decline as well. And if the investor didn't get out early, he probably lost a lot also.
IEO is the new hype, but only few are gaining their profits, mostly are the big whales.
You have learned the ropes already, so you gained better insights from this experience. You will not be deceived by the hype surrounding these IEOs again.

As you see what happened with the last 2 IEOs on Bittrex, I decided to quit Bittrex and never comeback. Since 2018 I realize that Bittrex is not a good exchange anymore. Low volume, low liquidity, supper slow KYC process and customer support. They did like they were trying to be the worst exchange.

IEO could be the new thing today, the only problem is that they are sold out the minute it has been officially released. Of course we can control the market and we really don't know what's going to happen.

And just like ICO there is risk involved, but what I like about IEO though is that it's has the back up of reputable exchanges. Maybe this is a plus for whether we will see a dump on it? We don't know.

So this is a continue battle and dilemma for most investors and traders.
