Simply, what is Bitcoin? - does China allow it?

Bitcoin explained in a very simple manner - for everyone to understand
(anyone who can also understand in English with a different accent).

If you want to understand more about Bitcoin, I recommend to you an interesting presentation @MIT by Andreas Antonopoulos (a Greek-British bitcoin advocate, tech entrepreneur, and author, teaching also at the University of Nicosia in Cyprus) - the presentation @MIT is from 2015: https://www.youtube.com/watch?v=J8y_GypCWf4

Source to look at and evaluate (whether is reliable or not) regarding the China 's position on the Bitcoin use/investments: https://www.mondaq.com/china/fin-tech/944330/regulation-of-cryptocurrency-in-china#:~:text=No%20PRC%20law%20or%20regulation,commodity%2C%20but%20not%20a%20currency.
