From just a business and investment perspective, what would be the more significant investments than what BlackRock and the other asset managers are going to bring if their applications are approved? I can't think of any other unless Russia and other sanctioned countries start buying Bitcoin and HODL them in their "vaults".
Let's hope this bold will not happen (at least not officially) because it would be the ideal vector of attacks on Bitcoin in the rest of the world. The implications that such countries would start buying larger amounts of BTC add fuel to the fire of those who want to portray BTC as something that serves these countries to avoid sanctions.
Of course Bitcoin as well as fiat can serve good as well as bad purposes, but the key difference is that the
"dirty fiat" has the support of every state that issues it, while Bitcoin is exposed to attacks from all sides and practically has no adequate defense.
