What do you think about Dutch Auctions for ICOs?

[paxmao]

A Dutch auction is short of an inverted auction, that was used in the Netherlands to sell goods, including tulips. Basically, you start with a certain price that goes progressively lower as the time passes.

Example:
Minute 0   - 1 token = 100$
Minute 5   - 1 token = 50$
Minute 10   - 1 token = 20$
Minute 15   - 1 token = 10$

etc... you get the idea. You can place your offer at any time and the auction ends. This is a way of getting the best possible sale price, which does not happen with a conventional auction, because the winning bidder may have been willing to pay even more.

Now, regarding token sales, is a bit less dynamic. You place your bid or bids at different prices. For example:

1 tokens at 100$
10 tokens at 20$

All users do the same, so there is a list of prices with an associated amount of tokens. The seller will start with the highest bid and start summing up quantities until everything is sold or the list finishes. Now, the good thing for the buyers is that they don't pay the price they have bid for, but the lowest accepted in the list.

So I have 100 tokens to sale. I go through the list (all user bids are grouped now by price and quantities added)

3 at 100                   accepted, 3 sold
5 at 50                     accepted, 8 sold
40 at 30                   accepted. 48 sold
40 at 20                   accepted, 88 sold
100 at 15               part-accepted, 100 sold, auction ends.

All users will pay 15 $

Now the question...Give it a bit of thought, what would you say about this mechanics for a token sale?
