On tribaldex.com, it costs 100 BEE to create a token; and why wouldn't you be allowed to trade crypto? In Europe, if I'm not mistaken, there is a 30% flat tax if you withdraw your crypto into euros.

Creating a token is legal; what is illegal is creating a scam. I state this in several of my posts: my token is not an investment token, and I make no promises.

And on Hive (via interfaces like PeakD or Ecency), you earn cryptocurrency by writing or voting; if you use specific tags, you earn tokens (via hive-engine.com or tribaldex.com).
For example, the "alive" tag earns you ALIVE tokens, the "cent" tag earns you CENT tokens, and so on.
