Thanks for the tip off @jondoe. I will monitor it, but as yet I don't have the spare Steem power to delegate to Upex compared to the return I get each day from my carefully selected curation trail (I follow the Koreans!!). As with any delegation service, you have to have money to make money though (or in Steem's case Steem Power to make Steem Power). I find Steem a real slog as a British Astrologer with an interest in Crypto. What I specialise in is a "niche subject" and it is very hard to get up significant up votes, as majortiy of the whales on Steemit are Korean or from the Sub Continent, and they don't have any interest in what I write about, plus they help each other out within their own community. What we need on Steemit as well as services like Upex is ultimately more diversity of users on a global scale, so that the cream can rise to the top, and we can all win. As it stands at the moment, with the Koreans voting for the Koreans, and the Bangladesh community voting for the Bangla community etc etc. That means that those on the margins will continue to struggle along until we do eventually get this platform humming, and that means making it accessable on the one device we all have with us all of the time - on our cell phones. The quicker someone can create a mobile phone app that is safe, secure, unhackable and easy to use, the better. Then Steemit will fly....
