Luno is a good and userfriendly wallet, we can make transactions in a wallet both to receive, send, buy, or sell our coins, all of which can be done inside the Luno wallet itself without having to send coins to other exchanges.
The security of the Luno wallet itself is very good, when making a transaction we are required to confirm 2FA with our personal mobile number, so that only we can confirm the transaction.
But Luno Wallet does not support crytpocurrency much, only BTC, ETH and Fiat Money, maybe we ask why there are only a few?
Of course that's not a problem for us, because what we want is good and guaranteed security for our Asset Storage Wallet.
