That problem is discussing in our team now and we'll come to a solution for escrowing the dev wallet next week. General idea is to lock all the sum and only release not more than 10% - 20% of total coin mined from time to time (maybe every 6 months - 1 year) and that can be tracked by community.
That's very interesting. I like this sentence from Dev. it will ensure to be fair with people.
When the exchange is available for trading , I will join to buy it later.
