Coinbase is the best online bitcoin wallet to me. In our country coinbase trade doesn't support, we just can use it as a wallet. You can send BT, ETH, LTC, BCH from email to email or address to address  If you go for email to email version then he must have a coinbase account too. Only too coinbase registered email can send and receive, and it happens in a second. Just amazing.

And, you can send or receive that currency by address to address. If you have still doubt then you may have a search in google or youtube.
