One of the shittiest exchanges in existence irrespective of the fact that isn't has lasted over 6 years, my account keeps getting logged into even after I have activated 2FA and changed my password several times, thankfully I didn't keep any funds in the exchange at the time, once had an issue with withdrawals and up till today, it has not bee resolved.
I am not surprised they never acted upon the 2FA concerns because they are really a bunch of low-lifes that for some reason have still not implemented their exit strategy even though they have selective scammed on a mass scale.
