Well, People are always quick to jump to conclusions even without verification. Did you really verify the negative thoughts about Bitcoin before you believe it was so or that was just out of what was been said? Anyways, it is good that you have now understood what Bitcoin is and I truly believe that we are still at the early stage even though people can again argue that Bitcoin has already gone too high in price not thinking where it could be in years to come.
I never jumped to conclusions pal, I only had my reservations at that time. And if you must know, most of these reservations linger till today, only that I don't care about most of them anymore. The better regulations and more traceable transactions of Bitcoin these days help me better to under-weigh the negative side of it.
That whole "Bad guys use crypto so let's do everything in our power to make sure that people never use it" kind of reminds me of the Edward Snowden situation when he leaked that the US was monitoring people's phone calls to prevent terrorism.
And you think bad people could be totally eliminated from Crypto? That is not possible. Even the most regulated fiat is still being penetrated by these people.
