The hacker agree the deal(100BTC for 50M NXT) because lots of people agree rollback in the beginning.But more and more people start to against rollback, then he doesn't need to continue the deal.
Depends what happens without rollback. Price will likely crater like mad - cashing out will be tough, and he has a crowd chasing after him. Not a great deal either.
If he goes with 100BTC he might actually get some peoples respect... and 100BTC aren't shabby for sure.
Stop storing your nxt on the exchanges, for heavens sake! You hurt all of us when you do so.
Well - BTER did all they could to keep money in their exchange. High withdrawal fees, and interest offers (much higher than forging fee).
Secondly people are also whining about the low liquidity - on NXT in general and on exchanges like HitBTC. Well - you gotta store your NXT there if you wanna trade. So which is it?
I think NXT should get a "lock account" feature - NXT accounts get unusable when the majority of the Stake decides so. That would prevent rollbacks but allow the community to punish hackers.
