Short run, has more volume and may make headway but longrun.. once hackers find a way or they have legal troubles then its back to square 1 for them.. i suspect its a shortterm play for them to get their money and run anyways.
Except that they're using fiat backing so hackers aren't near the problem. Transactions like that can be reversed AFAIK unless you have a network of ATM users + cards at your disposal. Not something a typical hacker would have... So in some ways, it could be safer.
Really you have to worry about theft without the hacked component. However thats true everywhere. Everyone claims they're hacked in these low margin businesses. I just SMH.
Well I suppose hackers could issue more of the currency on external exchanges ... lol. An hack that randomly inflates the money supply into the hands of thieves.
