1) As a constant reminder to market participants that bitcoin doesn't give a fuck what YOU want stored on the chain. Bitcoin is for enemies.

2) To increase the security budget. Everything is good for bitcoin.

3) To make Ethereum irrelevant.

4) It's the perfect expression of value for a bitcoiner like myself. The purest Bitcoin circular economy. You're literally buying and selling sats for sats.

5) It's lots of fun. Bitcoin gets very boring after a few cycles.
