I hold quite a few obits and as long as the dividends keep coming I'm happy with it.
If you want to see the price of Obits increase, take actions that increase the volume on the bitshares DEX.
Increased volume will generate increased revenue and increased revenue will generate increased dividends.
As dividends increase so does ROI - smart investors will notice and the price of OBITS will increase.
Volume is much lower these last few months then at the end of 2017, so dividends and obits value has been lower too.
Pick your favorite coin and place some market making orders - its a small step you can take to increase volume on the DEX.
