The sad part about this is that, "burning" became such a hyped buzzword that I see new projects starting with 1 trillion tokens and then burning 500 billion of them. Even if the coin worths literally 1 satoshi each, or even lower, that looks like they just burned millions or thousands of dollars at least. Which creates this amazing "marketing" for people who do not realize that starting with 1 trillion and burning 500 billion tokens is EXACTLY same as starting with 500 billion tokens, there is no difference.
I couldn't have said it any better. It's like ypu stole the words I'm about to say hehe.
...Thus, the developers are trying to reduce the total number of available coins, while the created shortage affects the growth of their value.
They saw the success of the coin burning pioneering projects and they wany to follow their footsteps.Most developers today have abused this unfortunately. They intentionally inflated the initial supply so they could create a fake "shortage" later on as el kaka22 explained very well.
Don't easily fall into this marketing trap.
