Today the same thing happened to me as to you. In fact, it even reached 3000$ and just as it came, it left.

Guys somebody just dropped this into my wallet.This coin is acting very strange going from $25 to $800 for the lot.Anyone else received SOS from an unknown source.Do I send it back to where it came from.Or is that what they expect me to do.
Update:The 1000 SOS coins mysteriously dissappear ed out of my account again.No trace in my wallet or history.
