I would not expect to see a half dollar in 2019. That'd be a massive gain from where we are right now. Anything is possible, but I wouldn't hold my breath for that anytime soon.
The company needs to continue doing what they're doing- placing machines, making sales, and increasing revenue. In time, they'll be in a much better position to negotiate a new deal/partnership/financing structure; or, grow their way out of debt.
I know the company is relatively silent. However, keep in mind this is still a pretty small company. They have a handful of employees and clearly a PR person isn't one of them.
A few extra sales and things could start to move here pretty quickly.
I know it's painful right now, but give it time and just be patient. At the very least we're way oversold right now. A little positive momentum such as a good 10Q should start taking us back to decent enough levels that you may be able to take some profits if you're avg is low enough.
I check the stock daily. But I don't obsess over it. I'll start paying attention a lot more around November 15th when I expect the Q3 report. Then we'll see what we have to work with.
