There are of course other options, I think we had some people just move their LEO to CUB when it launched and then PolyCub, I'm still buying. Leo is holding pretty steady these days with Hive, so just a little more demand and we start to eat through the supply. But time will tell of course.
I have CUB too, but it's a very different beast, and I really don't see any other communities competing with Leo.
