So far, Clubhouse is available exclusively to iPhone users, but an Android version is also promised soon. Another feature of the Clubhouse is the complexity of registration. Now the network resembles a kind of closed club, which can only be entered by receiving an invitation from a familiar user. At first glance, this should have limited the popularity of the service. In fact, this led to the formation of a black market for invitations. By purchasing an invitation to eBay or Twitter, you can become a member of the social network. Prices go up to $ 800.
