Current burn, may be a term for taking crypto assets and completely removing them from the ecosytem.

This is fictional, however if you had 1 million GA tokens and burned half the supply, that means only 500k are left.

In crypto you can send these to a "blackhole" address which can never be accessed, thus removing from supply, some assets allow for the conditions to be changed, but I have seen the blackhole method on other tokens.

Probably referring to when x anount of whacked crypto is burned y is going to happen was the take I got.
