This is my view on it: Keep 10% for dev team if need to hire more people.
10% for future community bounties etc that might help on promoting it.
80% Burn perhaps?
I have nearly 2k of COSS now and waiting for an ETH buy order to fill and I will munch on a few more with the 6% bonus.

If from 130 million tokens it goes down to even 20 Million, each token COULD be worth x 10 in marketcap once it hits exchanges lol.
