In my opinion, shitcoins are coins of no value. In real life, they are coins despite its exchanges, it will not generate or yield any profts hence it is worthless.
Yes a coin with no value and not providing any proof that make it worth in the exchange. Even if it is listed in the exchange and no product this will become useless and worthless. That is why mostly it become delisted in the exchange so let us become be more careful when investing to a coin to avoid lose.
