I agree that many exchanges lack security and are vulnerable to hacks and also severe breaches .The only way what we can do is either look for an alternate exchange or not storing much assets in on exchange .These are the only 2 ways what i suggest people as we have no other option as protection of assets is our take and point of concern.So i would also tell many well wishers that we are going to here for very long time how bear the markets will be but protection is utmost priority.
