Room for improvement #1: Even though Purse.io, and some of their more satisfied users say I should just send an email to *******@purse.io, for some reason, they do not use a ticketing system like all other, normal companies do, so I cannot keep them accountable, like: "Hey, have you received my email with a ticket number@#?"
They simply don't reply to email and are sitting on my money (bitcoins). I have no idea why I got locked out of my account in the first place.
Room for improvement #2: In general I feel pretty unsafe on their site, they could use much better security measures. I don't like 'hard coded' emails for the account, that is, the user cannot easily change her registered email. (Are you listening, SiteJabber as well? You made the same mistake.) I understand changing your email may have security precautions with a site, such as Purse storing money (bitcoins), but as an example, they partner with CoinBase, and CoinBase use much better security measures, you can get a verification code not only on the phone but in email as well, according to your preferences, how much money (bitcoins) do you store on the site, how secure you want to be or not want to be (security is always a trade off, as Bruce Schneier famously use to say).
Room for improvement #3: The ability to use a trusted, 3rd party escrow service.
