Just signed up for the web interface. Extremely confused. Please help!
1) How do I secure the webwallet? I was only provided with a pw and no private keys; how do I get the private keys?
2) 2) How do I use my BTC to purchase other coins? Does the web interface need some kind of connection with a local wallet like Parity?
3) There's a deposit feature for BTC. If this is a decentralized exchange, why do I need to deposit here?
1. The pw unlocks your private keys. Do not lose it, no one can reset it or recover it for you. Once logged in you can view your private keys.
2. Very easily - by using the exchange.
3. You need to deposit to the exchange - it is your wallet. I don't quite understand the second part of your question??
Other exchanges - Poloniex, Bittrex, Bitfinex, MtGox, etc - hold the private keys to any coins you have there. They are centralised; the coins are not really yours at all because you don't have the private keys. With a decentralised exchange, such as CryptoBridge, YOU hold the private keys to your coins, not the exchange. The DEX can never take your coins from you.
In the case of CB, you actually hold keys on the BitShares asset exchange platform. I'd suggest reading up on that a bit.
