What cryptocurrencies can be traded with capital?

Could you elaborate on which cryptocurrencies are eligible for trading with capital investments? It seems to me that there is a vast array of digital assets in the marketplace, each with its own unique characteristics and risks. For instance, some cryptocurrencies are known for their stability and scalability, while others are more volatile and speculative. As a potential investor, I'm curious to know which of these digital assets are typically considered suitable for capital trading. Additionally, I'd like to understand the factors that determine the eligibility of a cryptocurrency for such investments, such as market capitalization, liquidity, and regulatory compliance. Could you provide some clarity on this matter?
