how does it help anyone but yourself?

This is kind of a surprising question coming from you, but a good one nonetheless.

When people know when their network is bubbled and when it is deflated, not only can they make extreme profits, but in the process they also stabilize the network. The more people who buy low and sell high... the less volatility a crypto has. Less volatility means more stability. More stability means more trust. More trust means an expanding network, that inevitably bubbles again and the process has to start all over. However, every time it happens liquidity gets larger and larger and the network captures more and more trust and stability.

I'm a bit surprised to be having this conversation with someone who obviously knows the necessities of market-making. On the same note you clearly speak for a lot of other people as well so I guess it makes sense.
