Nowadays everyone know the Centralized and decentralized Cryptocurrency. If you want to clear example you can search Google, because already many times discuss in the same question so we don't satisfy in this statement. I think two years you are survive in this forum then why you not understand the Centralized and Decentralized platform.
I joined this forum as a bounty hunter and in this two years i wasn't active so much. But now i'm active regularly since couple of months and trying to understand about which i don't understand clearly. Yes, i can google it or search in youtube but i thought it's a good idea to discuss here because many people share their own idea which is easy to understand for me and i think i was right about it. And i'm extremely sorry if my question bother to you.
