Can someone explain Shibarium, Shibu, bones and the burn to me like I'm 5 please

As the title states. My bf and I purchased some Shibu a while back after having a few drinks. Now they are upgrading and talking about burning Shibu and bones. I'm so fucking lost at this point. I understand the concepting of burning. But like, do I buy bones? Bones which is apparently Shibarium? Bones are then used to trade for something? But im not sure exactly for what. It's really hard to find anything straightforward. Im attempting to follow their Twitter feeds but thats a mess in itself. Should we be buying and holding Shibarium or holding our Shibu? Blah. Lol
