good Wallet

Exodus would have to be my favourite offline wallet ATM, but there's a lot more options and Exodus doesn't have many currencies.
If you want to use an online walled, I'd reccommend either Bittrex or Cryptopia (the New Zealand one), as they're huge exchanges and therefor extremely unlikely to fall to hackers, as they have surely invested hundreds of thousands of dollars of their profits into security, as well as R&D.
I believe that they're safer than some downloadable wallets, as even those can be hacked -- but they usually haven't got thousands of dollars of R&D and security professionals working on keeping things safe.
