There are many differences between Bitcoin and other coins in the market. All other coins in the market are directly dependent on Bitcoin. That is, if you observe the market of other coins in the market, on the contrary, if you observe the market of Bitcoin, then you will definitely see the difference. When the value of Bitcoin fluctuates slightly, the value of all other coins in the market fluctuates. Again it happens that there are some coins that will dump in line with the Bitcoin market but when Bitcoin is pumping again those coins are not pumping.
I partially will disagree on this not all are dependent, some are independent as well. The term likely to be used is "Bitcoin correlation". Bitcoin is said to be highly correlated to as many cryptocurrencies, mostly the top ones but we can not generalize it to all. There are some cryptocurrencies whose price movement is not affected at all by the fluctuation of Bitcoin prices. Price movements on this cryptocurrencies are dependent on so many other factors including the potentials of the coin and what it was created to serve, since they are not decentralized as Bitcoin, partnership can also play massive role when dealing with the price fluctuations.
But in the end everything also remains the same regardless of whether it is called a correlation or whatever in one point everything (shitcoin) refers to the movement of bitcoin because after all bitcoin is the king so in this case we do not need to dramatize further because surely the focus will still be on bitcoin not shitcoin.
Although the strong statement about shitcoin stands alone for example but in terms of quality it is clear that the comparison will be very far when juxtaposed with bitcoin which in the end we have a definite condition where bitcoin remains the best and things like that cannot be debated anymore.
On the other hand, for now I think the discussion is too deviated because in the end our initial focus remains on collecting and buying bitcoin so that it will seem to make less sense when saying anything else, let alone the establishment of shitcoin which is said to be independent considering that it is too deviated from the initial discussion.
