It's good to see progress, but I'm worried about painting too much of a target on my back by using some of these apps.  Security is a significant problem until the issue of [blockchain privacy](https://steemit.com/steem/@zoidsoft/the-importance-of-privacy-on-public-blockchains-without-it-we-are-headed-for-hacker-hell) is addressed.  If Steem could have implemented private wallets, I would have invested considerably more.  I suspect that a lot of whales steer clear of this blockchain simply because of the lack of privacy and security.  I don't believe that wallet balances should be public information and because of that danger it poses, I'm forced to hold back on investing.
