It obvious that higher trading volum = more liquidity. liquidity refers to the ability of a coin to be converted into cash or other coins easily. Liquidity is important for any tradeable assets including cryptocurrencies.
Unfortunately, I have obversed that most coins listed this days on certain exchanges are without volume, that is, illiquid.
It is very clear that this situation was not common found before 2019.
What could be the reasons for this abnormalities. Your thoughts.
