End of 2024 was great for Bitcoin because BTC was hit all time high 1,00000$, but you can't say that 2024 was amazing year for altcoins, even after such BTC improved but there are no significant growth in altcoins price if comparing Bitcoin price. Bitcoin still very expensive but altcoins are dumping.
This day is remembered by everyone because in these last days the price of Bitcoin was greatly increased which even went up to 90k$. Their value has also increased but not so much, some coins have decreased and some have improved. Bitcoin has its own quality and development that makes people move to it, these other coins are just a risk that will succeed to Bitcoin, but they are not paid enough attention which is why they don't go up. When bitcoin price rises now and trades above 100k$ other coins will see good growth.
