Buywall and burn seems like the smartest way to keep everyone happy. Those who want to get out can do so, those who think the extra investment is going to help can stay. No one gets saddled with the result they don't want.
I really don't buy into the idea of buy back it looks shady to me and the price manipulation can occur also are developers going to burn the right proportion of investors token burnt in their own quota, I believe this is no, the team is just putting investors in dillema. The ICO should have been closed when the fund hit $3 million but decided to extend it for 24hours.
The buywall will be at the static btc price investors paid during the ICO. It will stay at that price for the duration of it's existence. The exchange records all ETT sold to the buywall. The blockchain records all ETT sent to the burn address. There is no price manipulation, or questions on how much is burnt, it's all right there on the public ledger.
The rest has been discussed several dozen times, including links of the posts made, the time they were made, the reasoning behind why they were made, and what really ended up happening, along with the response to that. They are all still there. This is the compromise arrived at, and it is going forward. Audits have already begun several days ago.
