When it comes to comparing Bitcoin and Shitcoins we need to have a look at parameters like scarcity. Only Bitcoin is really scarce, Shitcoins can be launched over and over again, even when a single Shitcoin has a max supply. Bitcoin is limited to only 21M coins and no Shitcoin can be scarcer.
So, in terms of scarcity, Bitcoin is king.
In fact, Shitcoin can increase the supply of third parties at any time and they are basically centralized and their supply system is controlled by third parties. They can increase the supply number at any time in the market as they wish and even take control of the market.
But in the case of Bitcoin, this system is completely opposite, especially the supply of Bitcoin is fixed at 21 million. No third party can take control of Bitcoin, nor can they increase the supply at will. As the demand for Bitcoin increases over time, it is becoming scarce due to limited supply. It is said that in the future, even holding 0.1 Bitcoin will become difficult.
