I think with them burning all of those coins and then giving a bunch away it will draw more interest in the project. Whenever those XLM hit everyone's Keybase wallets, there's a lot better chance for people to hold them thinking they may eventually be worth something now. However, it will probably not be good for the price in the short term with all of the coins that will be dropping.
It has actually caused a quick pump for the price of Stellar (XLM). That was 55 billions of Stellar (XLM) burned. That was a big deal to the Stellar community and those who are observing Stellar's development. That was billions of USD burned from Stellar's wallet. That was a big step done by the Stellar team. But then after the quick pump, it was followed by a red candle immediately. Stellar has to show more than just token burning.
