Are you concerned Bitcoin exchanges do not encrypt email? Or is this a non-issue?
Although bitcoin exchanges are doing what they can to ensure customer data and funds are being kept safe at all times, the same cannot be said for the way they communicate. Emails sent by Bitstamp are not subject to encryption, neither by the exchange owners themselves nor when the email is in transit. Kraken, on the other hand, uses GPG to encrypt all of their email communication. Is this is a situation Bitcoin exchanges will need to address in the future?
