I like to know the aim of putting up a plan to burn coins as against setting a lower amount of coin from the initial stage of project launch. Somehow in the future this strategy will not be attractive and cases of manipulation, hoarding and flooding of token will be revealed. 43% at launch looks unnecessary IMO
1) At launch Early investors have the opportunity of holding large quantities of token, if they don't sell at initial stage, they still hold same quantities even after the burn, which could results them have lot of fortune/profits after the burn.
2) if the token is reduced at the initial stage before launch, this will reduce the possibility of early investors having more token to them self. Which will in turn be a great hassle for them.
I most case, They might not even be able to make profits from their investment at the long run
