Sounds like a trustworthy exchange to me if they are notifying their users well in advance about up coming changes.
Bittrex trying hard to recover its reputation. They lost the No 1 position while ago because of the messed up created by their team. Check out the Trust summary & reference link for
richiela. These users know the forum and left feedback. There are thousand of Bittrex users who maybe don't know about Bitcointalk & still complaining about Bittrex on Twitter Reddit & other social media platforms.
Even I was about to lose .04
BTC because suddenly they blocked withdraw without KYC. Imagine You're using Bittrex for years and all of a sudden they locked your funds and never returns your money along with no replies from Support. Why they are providing good services to customers now? Because they have lost over 80% of customers to Binance. They won't exist if they keep doing horrible judgments with users.
I read some of the posts related to 2017. I had no idea Bittrex has so many issues. To be honest I am surprised.
Have there been any issues in recent times, say going back to the previous 12 months?
