* L - maximum bot level
* N(k) - number of k-level bots on the platform at the moment
* hold(k) - amount of tokens required to keep a single k-level bot running
Low-level license cost less. Each level has its limit of capital that the bot can manage.
The more capital you want to manage using a particular bot the more tokens you have to hold.
Each bot has a total amount of capital it can manage (on all levels) and a maximum number of it users. This mechanism protects bot owners from dimishing of trading strategy performace.
