We cant expect there will be many people come when sphere's progress is still small and its still a basic social media.
But they already hit the softcap anyway.
Well the future will show if they can get a major share. At least in crypto they will have good chances but for the regular users we will have to wait if the word will spread enough.
Social Media is a saturated market whether it is done through a blockchain or not. Even Facebook is losing users in drove. If Sphere doesn't pitch more on the virtue of their trading platform, it will not gain too much momentum.
