Congrats to NEM devs
Maybe finally their work has been noticed and the valuation of XEM [ksem :] is growing.

But...
how about the Exchanges.
Here has been few posts about their safety.
Is it expected that EVERY Exchange will be "hacked"?

If it is so, then I start believing that it is not actually a hacking problem.
It is just a systematic and 100% sure method to get virtual coins. And the method is owned by the Exchange providers themselves.
