The chart has run up and down several times, so you could have taken profits on multiple occasions. The big run is when $ANDI is acquired. That nearly occurred earlier this year, but the buyout price wasn't high enough. As more apps are approved on all platforms, $ANDI becomes a bigger and bigger acquisition candidate.
At this point in time the best guess at a buyout price is around $0.03-5 and possibly higher.
There are two interested groups:
1. A company that doesn't have the technology or stake in the apps market and wants in
2. Someone that has a stake in the apps market and wants to buy out some of its competitors
