Those prices are not forever. Once the bots return, things will change. The old pricing cycle is finished. Only a handful of bot owners have exited and the number of battles and daily active users has fallen considerably.
The challenge for the bots is renting for performance, not power and that's no easy task. The bots are generally uncompetitive and they were able to get their rating by facing other bots in the bot farms - win trading.
We're going to see how the ecosystem changes when the bots return.
