Bitcoin is the first and top cryptocurrency among other coins and is the father of other coins, and there is a possibility of influencing other coins including Altcoin.
and the reality in the market situation if bitcoin prices go down or red, other coins will gradually go down and if there is another coin going up or green it will eventually adjust the value of bitcoin not only Altcoian but all coins.
and that's my judgment, even though the reality is not the same.
