Siacoin's releasing a Lite wallet in a few days.

I don't know how or if this will effect the coin's price in the short term, BUT it's this type of development and activity that makes me a SiaCoin believer in the long term.

They seem to be making these advancements all the time, that will really pay off over time. They haven't made a huge oush in marketing, but I think they're keeping their powder dry till their infrastructure is set up.
