I know this is an old discussion but until now I haven’t seen an eloquent answer yet 
How can be possible that people supports Bitcoin if is
- mostly controlled by a few Pools ?
- 77% of the hashrate is in China and mostly generated by coal-electricity.
- If BTC at 40k consumes like a country (Argentina) we can imagine that in the short therm BTC cannot cost 200k without public opposition.
Thank you in advance for your opinions
