Thanks a lot @grandpere, I am also very happy to always follow your post, because very much new science that I get from every you post, about Cryptocurency. Honestly, I do not have knowledge about Cryptocurency, but after I read your article a lot, there's so much new science I can get. You are a teacher to me, and I really hope I will always be able to learn more from you. Thank you for everything, and hopefully you will be more successful for all your good...
