If we're talking about wallets, we're all acquainted with Imtoken, which was created in 2016 in Hangzhou, China. I guess Imtoken has been on my Android for about 3 years now, lol, but the wallet itself was founded in 2016. Imtoken claims to be the world's largest ethereum wallet, with over 4 million active users and support for over 30,000 ethereum-based tokens.
With the inclusion of three additional exchanges, Tokenlon, Binance, and Bittrex, Imtoken now supports exchanges in the wallet. So that we may more easily swap the tokens we desire.
This wallet has an excellent reputation since it still works well after all these years.
