I want to say thanks to authtor, very useful information 
Nice picture, bitcoin is getting more and more innovated hopefully many other people will contribute to bitcoin so that it will become more popular for the people to know what cryptocurrency is all about. anyway hoping too that other country will legalize bitcoin and help something to improve it more.
