Hello,
THe best option is to buy a ledger nano S. But until it arrives, you have two options: Desktop or mobile wallet.
Do you have a safe computer? Do you go to shady websites to download illegal stuff?
If you don't, I will suggest

I like Coinomi Android Wallet. Full Segwit.

Use coinbase if you want, that is still not the safest solution.

I know coinbase no good choice if we want to save much BTC
Else if you would ask me the safest way to store is a hardware wallet

I think I will not choice that dude coz we need always bring it if we want to transaction
