Everything you need to know about NFTs tokens

I traded these tokens and sold them when the market was in good demand.
I do not understand this market and what the buyers are guided by when they pay a lot of money for a picture.
If you understand this, you are already a millionaire
Some/most could be doing it out of ignorance, for their attractiveness or in hopes of getting wealthy. This is why I think it's better to create very useful thing and put reasonable price tag on them.
If you start making proper or very useful ones that really benefit people without a proper decentralized system, you could see people crawling out of caves demanding that NFTs should be banned or regulated. This is part of the reasons why I remain cautious. There are very useful things that can be done with NFTs or similar tech.
