How can I earn more BAT?

Could you elaborate on potential avenues to accumulate more Basic Attention Tokens (BAT)? I'm particularly interested in understanding strategies that may be effective for both novices and experienced investors. Is it primarily through trading on exchanges? Or are there other methods, such as participating in the Brave browser ecosystem, staking BAT, or engaging with advertising campaigns? Could you provide a brief overview of these options and highlight any key considerations or risks involved? Your insights would be invaluable in helping me make informed decisions about earning more BAT.
