How many crypto unicorns are there in 2021?

As a keen observer of the cryptocurrency and financial landscape, I'm often intrigued by the emergence of new and promising ventures in this rapidly evolving sector. One metric that particularly piques my interest is the number of crypto unicorns - companies that have achieved a valuation of over a billion dollars. So, I must ask, how many crypto unicorns have emerged in 2021? The past few years have seen an unprecedented rise in crypto startups, but the threshold of attaining unicorn status is certainly a significant milestone. With the crypto market experiencing both highs and lows, I'm curious to know how many of these ventures have managed to cross this threshold and establish themselves as leaders in the industry.
