Koinos is a free-to-use general purpose blockchain. Yes, Hive doesn't have fees, but it's not free-to-use and most importantly, it's not a smart contracts platform. To learn more about the important difference between free-to-use and fee-less, you can read my latest article: @andrarchy/fee-less-v-free-to-use-whats-the-difference
There are a number of USPs beyond the free-to-use aspect, which you can read about in our whitepaper.
We have a vibrant and rapidly growing community who you can meet on telegram and discord.
There are number of Dapps both live and in development. The atomic swaps are an app, there's KoinDX (a DEX), BurnKoin (a burn pool), koinosblocks.com (block explorer), and more coming. Of all the challenges we face, developers and user adoption isn't one.
Koinos is growing exponentially, people just don't realize it yet.
