As I can see all these things to manipulate BTC right? What are your thoughts about this?
How BRICS manipulates BTC price?
As far as I know, BRICS isn't made to influence BTC, it is to strengthen the finances of BRICS countries. If BRICS is getting stronger, it just brings impact on dollars, not on Bitcoin price. Bitcoin has nothing to do with BRICS, Bitcoin will always grow whatever happens in dollars. So, I think we shouldn't be so afraid of BRICS, only people who hold dollars must worry about the issue.
