At this current bearish market condition, we are seeing less and less people going into alt coins. In fact, most of them have not recovered a quarter of what they lost in January. So, it will be difficult to bring people even if the project is solid. What Sphere can do is to incentivize people who are investing now and will in the duration of the project.
Yes, the bearish market is crazy currently and somehow it seems to not recover soon. But maybe it was needed after the crazy bullride in December where every shitcoin went up at lesst 10x, but more like 100x or more.
