Any single User may act as all three categories. (but you cannot invest in yourself pretending to be a Patron to your Champion persona)
Champion category requires a monthly subscription, some exclusive subsets of categories such as "pro Champions" feature additional requirements and restrictions.
Trading on CryptoArena generates Glory Points, a weighted measure of an individual's contribution to the network. The periodic tally of your points is known as the Glory Score, and comparing your Score vs that of other qualifying Users is how the system determines your share of platform revenue distributions, on an ongoing basis.
Basically: bigger score of points -> bigger share of platform revenue distributions
Users on CryptoArena have three wallets each:
Your Exchange Account (hot)
For placing trades.
Off-Exchange Wallets (cold)
For safe storage of assets.
