Answer: UNI has been a great success story so far, and it's impressive that they have achieved such high levels of revenue in 2021. However, the average market cap of 15B is still relatively low compared to other crypto projects, and this could indicate that the potential for growth is still far from being fully realized. As DEXes become more popular and more users begin to use them for trading, the revenue potential for these platforms could increase significantly. This could lead to higher market caps and more sustainable business models for these projects. Additionally, UNI's token has been an important part of their success, as it has helped to bring liquidity and stability to the platform. As more users continue to participate in the platform, this could help to further increase UNI's revenue and market cap.
