About 2 years ago, i heard the bitcoin for the first time of my life. It was a blog about deep web and in the blog it was being told that " bitcoin is the money for the serial killers, drug dealars". and for two years i assumed bitcoin can br used underground deals only. I did not know people can invest money to bitcoin, and i never heard about altcoins till 6 months ago.
Now i know that, bitcoin can be used by anyone on the planet.
