First respected student Thank you very much for taking participate in Steemit Crypto Academy Season 2, Week 1 course class..

i have read your assignment very satisfactorily, there are many grammar,spell mistake. in last question,you did not clear that how we came to know after checking that which coin is centralized or decentralized . some text is looking rewrite

suggestion : always try to write in your own words after understanding the topic, this will lead to gain good reward

thank you very much for taking interest in my class
