i think at the moment almost all social networks are similar at the platform level, facebook is a bit above only for the vast number of registered users, i think sphere will be successful if they can offer a large amount of services and options and mobile apps lighter and faster than competitors
Maybe they can implement some games on the platform like facebook did. Their token could be supported by this games.
This is a great idea, many mobile games do have its own currency, so implementing those games/tokens with sphere system can increase traffic.
Seems to be a nice idea, but if the exchange rate will greatly fluctuate, it will be difficult to attract people to invest money into those games
