Update. Looks like a total of $23.5m was(were?) stolen ($10m of bancor tokens were quickly frozen before it could be moved) .
Seems like every week Another exchange gets rektd by hackers and this seems to happen just as prices start to go up. Coincidence??
I've said this several times, if you're not an active trader, Do not leave funds on exchanges. You're better of keeping your tokens in a Ledger nano S or trezor (seriously buy one).
