What are the cons, risks and downsides of investing in Cardano ADA cryptocurrency coin?

As with any technology or investment, there are potential downsides and risks associated with Cardano. Here are a few potential downsides to consider:
Relative newness: While Cardano has been in development since 2015, it is still a relatively new cryptocurrency compared to more established players like Bitcoin or Ethereum. As such, there may be uncertainties and risks associated with investing in a relatively untested and developing cryptocurrency.
Limited adoption: While Cardano has a growing community of supporters and developers, it has yet to achieve the level of widespread adoption of other cryptocurrencies like Bitcoin or Ethereum. This can make it harder to use or trade compared to more established cryptocurrencies.
Complexity: Cardano's platform is built on a complex architecture, which can make it difficult for some users to understand or use. This complexity may also make it harder for developers to create new applications on the platform, which could limit its potential growth and adoption.
Competition: There are many other cryptocurrencies that are competing with Cardano in the marketplace, including established cryptocurrencies like Bitcoin and Ethereum, as well as newer competitors like Binance Coin, Solana, and Polkadot. These competing cryptocurrencies could potentially limit Cardano's growth and adoption.
Regulatory risk: As with all cryptocurrencies, there is a risk of regulatory intervention from governments or financial institutions. This could include restrictions on the use or trading of Cardano, which could negatively impact its value and adoption.
It's important to conduct thorough research and carefully consider the potential risks and downsides before investing in any cryptocurrency, including Cardano.
