Inactivity
In the cryptocurrency landscape, the reality is that thousands of cryptocurrencies exist, but only a fraction of them gain significant traction. Many projects are abandoned or were merely gimmicks from the start. Consequently, it becomes inevitable for exchanges to delist cryptocurrencies that no longer generate customer interest.
It may seem unfair to low-volume coins, as they may not have had a fair chance. However, crypto exchanges have a responsibility to cater to active traders. Delisting stagnant coins enables them to concentrate on those that people are actively buying and selling.
Therefore, if you hold a coin with low liquidity, there is always a risk of it being removed due to lack of usage. The best defense lies in project developers fostering community involvement and increasing trade volume, as exchanges require sufficient activity to justify keeping a coin listed.
