There are some corrections that need to be made here.
- You are correct about the seed money. All current payouts and salary and operating costs are coming from the $20 million seed money and from people that buy Lino directly. Discord was started the same way and eventually sustained itself through an optional subscription service.
- DLive is an ad-less platform. There are no plans to generate revenue using ads.
- DLive doesn't take a cut. The 9.9% taken from every donation is distributed as daily rewards to Lino wallets that have "locked" their Lino points.
- Lino isn't a mineable currency, but you can run your own validation node and help process transactions: lino-network/testnets
Dlive originally wanted to run the whole service peer-to-peer, but currently they are hosting it off of AWS.
LINO was very smart about how they created their service. To become a partner, you are required to "lock" 2000 Lino from your wallet. This introduces users to the concept of "locking" points. Anyone that has locked points will receive a portion of the 9.9% LINO taken from every donation. The amount that these users receive is based on the total number of locked Lino and the total amount of Lino put in the daily "rewards pool" from that 9.9% of each donation.
This is an inflation concept, similar to what Steem has. The reward payout is based on how much Lino is locked and how many donations are being made. They want to get users to continually keep locking in their Lino (with the temptation that they will be getting a larger cut of the daily rewards), when the truth is that users will have to keep up with inflation over time by locking more and more Lino for the same general payout. This way, they trap users into locking all their profits from donations to keep up with inflation and this reduces the overall amount off Lino they need to payout until much further down the road (once they have enough users that people purchasing new Lino can cover the costs of payouts).
Its not a scam. Its not a "ponzi" scheme. Its success will be determined by the ability to grow the service enough to keep it relevant and to get people to pay for Lino.
Maybe it will be successful. Maybe it will fail. In the meantime, you can just collect your payouts as you go so there is no risk. Just be careful about how much Lino you 'lock', because all of that would be lost if they shut down sometime in the future.
