There are many winners as well as losers in 2021 but since I would like to pursue more on positive developments, I am quite amazed at many good things that happened in this year and I am hoping that it can even be more in 2022. I will always remember the official recognition - the first such thing - of Bitcoin by a small nation named El Salvador. Of course, Bitcoin experienced its ATH this year and though there is a dip right now am sure that 2022 can be performing much better...and the same is also true with Ethereum despite its biggest problem on transaction cost. We lost China but things turn out to be good because mining is now dispersed.
