They are clearly the market leaders in terms of online btc wallet. What are the alternatives?
Jaxx
Exodus
Electrum are few SPV wallets rather than blockchain.info like web wallets but they are better than any web wallets and easy to use as hot wallet.
Btc.com, viabtc, block.io and many more provides web wallet service but I don't trust web wallet as much as I trust SPV wallets.
