If Jaxx is not save, then does that mean all the mobile wallets are insecure? Then where should i keep all my coins?
As it is, it is very unsafe if you keep your coin in a mobile wallet. Because any mobile wallet must be vulnerable to account break-ins because it is vulnerable to viruses. It's a good idea to save your coin in a desktop wallet that is more secure than mobile wallet. I've tried it and I think it's pretty safe.
