I think that QuadrigaCX has nothing to do with the current situation, because problems with withdraw are reported back in 2016, and possibly even earlier. I posted link (post 2) with thread from 2016, nothing is changed since then, they receive money from user exchange account and then refuse to pay them. In the same time they obviously paid for their promotion as a serious company in reviews like this one, but we should definitely read the comments below article that we actually see what it is all about.
I see that info on their site is say Switzerland, but in review link I posted company headquarters should be in Panama? Also Crypto Capital is owned by Global Trade Solutions AG, which has no good reputation.
