That's the deal. The security hole is in the coin and the attacker is probably taking it as a challenge to kill C2 for a third time. If the extra coins are not burned, then I don't blame him and I won't help to stop him. I do know what the hole is.
Nope. Proof-of-concept attack done (
1/
2/
3), enough for me.
I got about 100 BTC from NC2 and decided to leave these kids with their
oh-so-innovative shitcoin.
I even tell em
how to stop me.And I do not aware of any security holes in C2.1 except
this one (well-known to all but C2 "devs").
But (!) if you do know some interesting vulnerability, share it and we'll definitely make some fun

It's not the coin that's innovative. It's having me as a member of the community that makes it awesome.
Try to keep up lad.
