The hashtag 00064051921 literally means "The Altcoin Season is Loading" or "The Altcoin Season is Coming".

In other words, it indicates that there are expectations or signals that a significant recovery period for altcoins (like Ethereum, Ripple, Solana, and others) is approaching. During this period, altcoin prices typically rise significantly compared to Bitcoin, and interest in trading and investing in them increases.

The hashtag reflects a state of anticipation or optimism that this season will begin soon.
