I think that you should not consider these three events in one topic, since they all have different weights, different consequences, as well as different motives. I think that the IDAX exchange is just a big fraud, but UPBIT really did it all out so it seems like its a real hack, but I dont really focus on it because it doesnt give me anything, its worth thinking about my problems, and these guys a lot of money and they will cope with their problems.
Why did you get the idea that the IDAX exchange is a scam exchange !? Why make such high-profile statements if you yourself cannot provide any evidence. Surely you just took it all from the Internet and now you are writing to us here. Just treat everything as an outside observer, think about how it could be that the exchange that created its name for several years at one moment will turn out to be a fraud, rightly, nothing. Its just that this news was released by people who dont want the good of IDAX.
