I would say over 80% of Bitcoin's market is gambling, and scams.
It's hard to stay away from gambling if you own Bitcoin.
Your statement is so incorrect on so many levels that it is even hard to begin explanation. Basically you are repeating utter bullshit that is mainly used by gamblers, thieves, terrorists and Mike Tyson.
