MintPal essentially assassinated themselves. They had the market lead, everything going for them, and...... they just threw it away. They really SHOULD have known better.
Huh? Obviously other exchanges are just as scared of the same thing happening to them. This is hardly flat out neglect on MintPal's part. I doubt they will see much of a decline in trading volume as the bottom line is, end-users didn't lose their coins (because of the dev's roll back). So MintPal will probably escape this a little wiser and pretty much unscathed. The industry as a whole will benefit from what they will learn about this security breach.
