There are many wallet services that are good for us to use as a storage tool or for conducting coin trading activities. I have lots of wallets like Indodax, Luno, BlockChain, Bittrex, Coibase, Trade.io, XAPO, Trezor, Exodus, Electrum and so on. But I only chose to use the 2 favorite wallets that I use most often, Electrum and Trezor.
Trezor has advantages in terms of security which are associated with third parties namely Electrum and Copay. I often use Electrum on smartphones because this wallet is the best that carries an android application with the main security in the form of a PIN.
