As I see they burned 36,4 million unsold tokens from the private sale, lowering the total supply of JRT to 383M tokens. And they going to use part of exchange revenue (after launch) to buy JRT on the open market, and will then burn them. This looks like very good, as value of tokens will be increasing
It is around %10 and not a huge difference. But it is a good way to show people they are keeping their promises. I think it is more important than token burning. We need teams that delivers.
