If you want to use online wallet try https://blockchain.info/wallet/#/ just because it is one of the oldest and most trusted online wallet.It support Bitcoin and and from recently Ethereum.I use this wallet just for short time and I still have account there, have no complaints and everything is working right.
What it is important that you use unique password when creating your account and to take all the security measures available,online wallets are most vulnerable to hacking.Therefore, if you want to keep your coins safe it is better to use desktop or hardware wallet.
