If you buy some stock in microsoft, you think they burn the dollars you use? lol
Yes. (I don't even bother answering this)
The current core devs of Lisk (Max & Olivier) get the donated BTC & XCR. The donators get their LISK. Max and Olivier will use every donated BTC and XCR for Lisk.
So if I understand it correctly, Max and Oliver will receive between 1 and 3 (just an estimate) million $, and 4 million list each.
I have multiple issues with this. When counterparty was in the same phase, they wrote a blog post explaining why they choose proof-of-burn.
http://counterparty.io/news/why-proof-of-burn/The biggest issue is that value is created out of thin air like this, which is unsustainable. There is simply no point sending further btc to the ico. Some simple math (please ignore the incorrect starting numbers):
Now there's 2k btc paid, with 80 million coins to be distributed. If people add 6k more btc to the ico, it will each 8k, and the same amount of coins will be distributed proportionally.
But what if ico finished at 2k, and the 6k additional btc was added as a market order after the ico? Price would be statistically the same (same amount of btc went into the lisk market), but profit distribution would be different, as all the profit that would go to Max and Co. would be spread between the ico sponsors.
And the biggest difference comes here. Max and Oliver will realize the BTC profit immediately (well it's not their choice, that's how the system is set up). In the second case however, people will not necessarily realize their profit (they will partly stay in lisk, despite the price increase), which will result in a higher market cap.
So please, read the linked blog post, and think about proof of burn. It would give an incredible amount of legitimacy of the project. Oh, and it would legitimize the 4-4 million lisk as well a bit (it would be a justifiable sum, but on top of $1m+ it definitely isn't)
