After last updates I have to write this feedbacks about idena itself. I will take it from 2 points of view. I hope I am not doing any fud, but just saying my opinion.

I. A general hungry moment from the developer.
1. A few weeks ago we had an important update where the newbies status was redifined, the human status introduced and the invitations were established. As I saw at that moment it was that it is a damn mistake.
Now I see that as the network grew fast the developer was looking for more rewards for him. As the invites were redifined, he made a way that the foundation address still takes half of the minted coins rewarded. Because of the lazyness of his spending all the invites he has available.
People have to be aware that each invite dev is not sending, he still get rewards. Each invite dev sends he still get rewards. And those rewards cut from the share of us as users.
This ain't a problem right? But they already have 40 milliion idena premined. It's god damn 40 million. But who cares!?
2. After the last update 216 verified users with over 3 epochs woke up with the revenue from invites being down. Why? For now it seems there's no reason. But, the invites in general as the network grew should've been with 100 more than now. What they did? He made the minimum solving score for short flips to be over 90.74% speaking that the humans need 92% and they have from start 2 invites. Does this seem fair?
Let's look deeper of how the network works. Most of admins from discord/telegram say that it is because of flips, this will make users forced to make flips. This is the most stupid argument and the most often heard in the channels of discord/tg. Why? How come that a user that is old is to blame for something that a new one makes? But again this update is an advatange to the dev, as his invites are more as the number of nodes increased, being capped to 500 (but the minimum not reached yet), more rewards for him. Cutting rewards from the members of the community and more to him.
It's totally obvious that both of updates are in his advantage. You might say that is not the case, that I am mind fucked, but if you look at the explorer 45% of the minted coins for last 6 EPOCHS, goes to the foundation address.
3. There is no decentralysation. I wanted to expect more from the team that every voice can be heard. They added a big percent of voices to the humans, elders whatever, but they don't listen or think of the future of the newbies coming along. For now newbies don't have any ammount to receive if they don't reach the 3 epochs. Against of what I said before in this thread it seems, newbies try a lot to get through the steps to make a bank of dna. but the current system makes everything from preventing them growing.

II. Sugestions to the current situation

1. Change the way the invites system work
For some time invites seems to be an issue. How to send them? To whom to send them? Most of the users just get the invite and they don't join the network, or miss validation. Do a system in which users are more responsabile for their invites. Create a % over the network's approval rating of new users coming and if you are not able to find the right people to join, you're losing the invite right. Myself I had 9 invites, 8 gone through and most are verified right now, still active members of the community. Buying/selling should be allowed as collateral. People should deposit a specific ammount maybe, a smart contract as a collateral for their verification; release once they reach 3 epochs.
Both systems can work if they are taken in the consideration. This system should also affect the foundation address, dev will not be able to generate 200-300 invites each epoch.
2. Cut the flips for the newbies.
When you join the network or you find about it, it's normal you don't know all the fking stupid rules added each week and most made by the community with no clue. There is no information, the information on idena.io is outdated, the telegram pinned message is stupid and the flip school is a stupid joke. Even more you can be in the case, you can't join the telegram channel because discord fails you to approve the 6 channels to gain access.
When a new person join, he firsts downloads the wallet and that's it. He doesn't know how it is mined, what is the validation or anything. The idena.io is not helpful, the information is not made for normal people, telegram people are idiots not being helpful enough (ok, don't want to generalise but I have in head a couple of admins.). People not going for information is the problem, the other problem is that there is no information.
How are all these regarding to flips? People see the flips, but they don't know how to solve them or how to do them. You need to look up for youtube videos to understand that the verification is at the same time to everyone.
Most of people understand that once you get the invitation, you will become a node at that date. They don't understand that you will need to do something after.
About flips, once you get all the info and you pass a validation, let's give the newbies 1 epoch the right to do 1 flip. If they do it and gets consense, let's let them do 2. If 2 are good 3. If all 3 are good, 4 and they are verified. 5 as humans. Don't give people penalties for the information you are not offering. There is no information out there. Cut the rewards they get now by not letting them do flips instead of giving them penalties for what you are not able as team to offer to them, information.
3. Delete the rewards for not spending the invite
To help increase the network create a rule as a % of invites available have to be spent if not a penalty comes out. To help and promote more and more the network. The stable users and active have all the time to have a percentage of invites giving out. This will also create a flow with the 1st suggestion as if they are not doing it enough well, the invites can be deleted or get a penalty.
4. Increase the short session.
Increase the flips on the short session and the time. There is a big cultural problem right now with the flips on the short session. I had a flip that works only for the way assians do checkin to flights. In europe, we don't have that. I knew only bc I travel a lot to China/South Korea. Making more will change definetly the way the score it is and how penalties can come to the small % solver, the update to 6 flips were well welcomed but there have to be more.

That's it for now haha, just my own ideas, i hope it helps someone or the project, sorry if there was any fud but that's how i see the things. This is a project with so many things to offer on long term but as now, some systems are not fair. I have many more in my mind about other features but I thinl this is enough for now
