"bitcoin is one of the biggest potential to make us become rich in quick time"
Bitcoin is indeed a get-rich-quick-scheme.
there are always idiots who use things in a different/wrong way than they should be using them, that doesn't make those things wrong. it makes their usage wrong.
i saw someone kill with a kitchen knife, does that mean you are a murderer because you have kitchen knives at home?

Wow - you defend Bitcoin the same way some Americans defend why they need to have guns, with the result being an extreme amount of mass-shootings. I have no idea why you wanted to put Bitcoin in the same context as mass shootings, but to each his own I guess.....
