Hi guys,


New to all this,

I apologize for stealing value right of the bat, but I before buying anything I'm doing my homeworks where people know what they're talking about.

I'm based in Japan and using coincheck.com as trading site and wallet on my phone.
I read a few pages about attacks and theft of altcoins, and I was wondering, when you have coins online for trading, but also fiat money there, if the site gets hacked and the coins taken, will your online USD or yen or whatever also stolen, or is that a different "vault" / process altogether?

Thanks
