An Italian cryptocurrency exchange called BitGrail says it was hacked and some $170 million worth of a currency called Nano is missing.
Hackers are very annoying, really. They challenge themselves so they hack as many as things as they want to know there limits. It is really sad to know that these hackers exist. Instead of helping the economy, they let it fall. I sure hope that bitcoin won't be hacked to save our money. This is one of the disadvantages of cryptocurrency.
