Great news. Finally we can something positive among all these bad news and huge price drop in recent days.
Adding of USD is huge step forward by Bittrex. When they will enable new registrations, I can imagine how many people will sign up on Bittrex. From my own experience, support of Bittrex isn't very bad, but it's great to hear that they are hiring more staff and preparing for huge wave of new users. And I hope that after adding of USD to their exchange, they will get rid of USDT completely.
Why great news? It takes weeks if not a month to receive information back from their support team if you ever get in need to contact their support. It is good news for bittrex of course they are doing all the best for their exchange to start to pick up volume and earn on trading fees. I don't trust bittrex much tho, I've been reading that some people got their funds trapped after they haven't noticed that they will require IDs and some people submitted ID and weren't able to withdraw still + support seems slow. I don't have any experience with them as I don't use their exchange, was using it in the past and all was smooth, but after hearing complaints it tells me that they don't value their customers as much as they value earning money. They've been acting a bit shady lately.
I can't speak for others, but I didn't had bad experience with Bittrex. Support always answered my tickets within a day or two. Last time when I had to contact support was over month ago, I don't know, maybe things had changed since then. Yeah, there was some issues with ID verification and it affected reputation of Bittrex. But so far there are no exchange without any cons - some have terrible support, some are very laggy, others involved in shady activities and etc. In my eyes Bittrex have least disadvantages among other exchanges
I just checked and bittrex is not open to new accounts unless you are a corporate client or a select invitee, so it's not open to people in general. I am unable to open an account with them as are most ordinary people. Even with corporate clients they are saying they can't guarantee to open an account. So it really is very limited. I also know they are not responding to support tickets for over a month, if at all. So overall it's not a good place to be as far as bittrex is concerned.
So far they didn't announced date when they will enable new registrations, but according to announcement it will happen soon.
