I think this is another strategy to promote a project and draw people concentration! If any new project is good, then they don't need to announcement of burning their coins! but they did cause they know, due to such news,, people will buy their coins crazily and thus project volume, price and liquidity automatically increase even before burning has done! Cause we all know what will happen after burning a portion of any coin!
A surefire trick of not giving information about the team's upcoming burn and seeing a surprising rise for everyone. that's a good thing about what they do. but indeed their strategy is to get people to buy coins that will be burned. A good project will think about it in detail to make people think more about what they are going to do.
