I'm with everyone in the comments - I don't think burning makes sense, other than impatience.
Although I did burn some Rusty Androids a while back just for the fun of it!
But I just think holding them makes more sense, and if you must sell, just stick them on the market!
Yep agreed on that one.
Although the legendary gold foils are hard to sell and they have a nice amount of DEC.
Most of the DEC created from burning is from those.
