because the number of projects is very high competition, it takes hard work to attract the interest of many people. at least they have to do significant development
There is definitely significant development happening here. They just released the new mobile App in public beta, which is a full-node mobile app with full convergence (so desktop version and mobile version are actually the same program!). That's a big deal IMO, it allows users to stake coins on their phones and opens up an entirely new target group of people who only have a smartphone but no PC.
