Liqui exchange was closed due to the lack of liquidity as was explained in its official announcement. This notification was published in January, 2019.
Customers of the exchange had been able to withdraw their funds during 1 month after this notification was posted.
Sometime I have to wait a day to get the feedback from the support. It's not the strongest part of the exchange, I hope, they are going to do something with that
I see, that liqui is not so active in promotion. It deals with a big number of coins and also it allows you open a saving account, that's quite interesting proposal. But I don't see a lot of advertising of the exchange, it deserves more traders.
I used to have the problem with the confirmation letter when I tried to login in. I opened a ticket, but surprisingly it was resolved quite fast, I thought it could take some days or even week, but support answers. Good job
