When we talk about the damage, lets put things in perspective.
We are in bear market and prices are bottoming, so the real damage is actually much much bigger.
cryptopia has faced other hacks before, am i right? but never of this magnitude?
so they were able to hurdle problems that arose from previous hacks like maybe pay off those who legitimately lost their cryptocurrencies to a hack? wonder how they'll deal with this latest headache...
i started with them sometime early 2016 and didn't have problems other than delayed transactions at times and not so prompt customer service responses (also sometimes). and as far as i know, they've always gone back online after a reported hack/breach which was probably just small-scale coz they got back quick...
but this one is different so, given that this experience will hurt their reputation if they turn back online, i hope they invest in or find a way to quickly identify suspicious activities within their site in the future. i still think they're a better choice than other medium-level exchanges. i agree with you when you mentioned that their ui was easy to use. that's one of the reasons why i like using their exchange.
