It's not directly supported by Larry Fink but Blockchain revolution and tokenization of assets is, where Avalanche is having good partnerships already, like JP Morgan or Deloitte:
JPMorgan tests tokenized portfolios with Avalanche blockchain tech
Deloitte Partners With Ava Labs To Leverage Avalanche Blockchain

It's all about tokenization of real world assets and Larry Fink's article is a very good read, where Larry Fink sees really big benefits of tokenization and it will be a huge boost for all coins who support it.


It's a big opportunity for Avalanche because of tokenization of real world assets. And Avalanche is a leading cryptocurrency being able to have a good chance in a crypto-based "technological revolution", as predicted by Larry Fink because Avalanche’s goal is clearly to tokenize real world assets and Avalanche is really having a leading technology to do so.
We will see many cases, where tokenization will be a true, groundbreaking innovation and be a hot topic for various opportunities.
Larry Fink has not endorsed Avalanche directly.

If you realy want to kno why it's so bullish, you need to do more research, I'll give you 2 links here of already existing partnerships and more is about to come because if you also read Larry Fink's prediction it will be a true revolution many people don't know yet about.
And Larry Fink is a really big player, he knows what to talk about.

You are right, Avalanche is a real and unique L1 Blockchain.
Many people call Avalanche a token but Avalanche is a coin.
