How about fixing the web app before adding more features? Their Ajax page loading hangs most of the time. Going straight to the URL works immediately, but it's not always possible.
Why is multi-sig in quotes? Is Coinbase providing its users with a '3' address that is on-block chain, or does this "multi-sig" approach still reside entirely off-block chain.<p>Edit: I presume that Coinbase still holds on to all of the private keys for Vault accounts. Can someone verify otherwise?
Multi-sig is a very powerful innovation for corporate use of bitcoin. Not because you can have arbitrarily many M of N signing a transaction, but that you can outsource complex policy in a trusted way. E.g., create policy that lower level employees can control a small percentage of a company's holdings, while higher level employees can control a higher percent. It allows you to implement flexibility that exists in the credit system, without giving up the trust/control that comes from the blockchain system.
What's up with the cold storage? That is absolutely no security, it is purely an operational detail on Coinbase's side. You are still trusting them with all your coins. Once they get multi-sig, that might actually be something interesting. For all we know, the "Vault" might just be a new menu item and some css.
Is anyone else picturing the digital equivalent of this Al Pacino snl video? <a href="http://kristenwiigdaily.tumblr.com/post/27009841161/mygiftismysongand-snl-al-pacino-checks-his" rel="nofollow">http://kristenwiigdaily.tumblr.com/post/27009841161/mygiftis...</a>
I disagree with the direction Coinbase is going. Of all the things they could have built next, this is what they chose? Why not develop a button that says "Pay with Bitcoin by Coinbase" that allows one-click payments on third party websites/mobile apps? Or why not compete with Bitstamp and btc-e on the exchange front? There's definitely tons of room for competition there.<p>Consider a traditional USD/EUR bank account. If your bank offers you a "vault" option to store your large balance to offer better reassurance that it won't get stolen from your "regular account"/wallet, aren't you going to have some serious concerns about security of the regular account? Instead of offering a "more secure account" why don't think just work on the fact that people feel that their regular accounts are insecure. This seems like a bandaid on the problem rather than the proper fix.<p>It's also overcomplicated. Now I have two account types and have to worry myself over what the differences are for accessing my money in each and how to use each. They're increasing the amount of friction it takes to get started rather than basing their model off a bank's model of "your account is as secure as it needs to be, just use one".
