Altcoin season is the time when other cryptocurrencies like Ethereum, Solana, and others start to grow faster compared to Bitcoin. This means that people start investing in altcoins instead of Bitcoin. When Bitcoin's market influence decreases and altcoin prices begin to rise, it is referred to as alt season. During this time, more people trade these crypto coins, leading to further price increases. In the past, when Bitcoin went up, shortly after, altcoins also saw significant gains. Similar signs are appearing now, so many investors believe that a good time for altcoins may be coming soon. But remember, the crypto market is volatile, so make decisions wisely.
