You will have to put money to the exchange in case you wanna trade stuff and it's like banks too. And they take fees. So there's too many worries about e-wallets that are not needed as long as you keep btc at Poloniex. You will withdraw it to dollar anyway so what's the point of any e-wallet anyway?
Thank you for your comment
Renegade1979. With Deluge, you don’t need to withdraw anything to dollar. With our patent-pending technology, you can use the value of your Bitcoin directly onto the Ethereum network and vice versa. This speeds up the exchange process considerably as compared to an exchange like Poloniex. The wallet simply provides an user friendly UX that you can use to send Bitcoin, to say, an ICO smart contract on Ethereum.
While this conversion will cost you about 12-24 hours and 2 sets of transaction fees on an exchange, Deluge will do this in about an hour with only a small trx fees.
