Its all relative if it used to purchase anything that can be dropped at random then it is actually not that valuable. The only way I could see this being valuable is it would take someone months to find that many bits. Also, if its possible to run out of ammo because you do not have a 'good' enough gun to kill the enemies in a certain amount of shots that would make it worth it. Would like to hear from someone with some insight to what they will actually buy, for example one upgrade for a gun or 10 or 200.
I would also like to know exactly what we will be able to buy with these "bits"
