if you say this who using bitcoin are stupit i think who can say this that person can be stupit or crazy , bitcoin is useful and we can do with bitcoin eveything ,how can you say that i couldnt understans it is meanless.
The fact that you can't spell "stupid or understand" kinda worries me that you use btc so casually and are not worried that you could get scammed so easily, bitcoin scares people because a lot of people know they cant handle the job of learning the fluctuation.
