The further you dive into world politics and the global dynamics of world and individual (country based) economics you’ll see there are no black and white answers. BRICs catching up (and in some areas overtaking) was long overdue and has benefitted millions or even billions of people.
Some of that success, especially in regards to India and China is based on huge sacrificies for freedom and human rights in general. Ofc it’s a concerning topic, but at the same time western „democratic“ countries struggle with similar isssues, so I would be very careful to look at these things via a simplifying-lense.
It’s tempting, because it seemingly explains the world situation in an esier to grasp way, but ultimately fails to describe reality.

Last note, BRICs do already impact crypto, yes, but a lot is still subject to change.
