Why do altcoins only explode in the middle and late stages of a bull market?

Funding issues: The altcoin project owners lack funds throughout the entire bear market to the early stages of a bull market. They need to pay salaries and expenses every month, and can only cope with it by selling coins every month.

Fund flow: In the middle and late stages of a bull market, when big whales have made enough money on Bitcoin, some hot money will flow into the altcoin market, creating a bubble altcoin season, which is both a carnival and a wave of harvest

Shipping strategy: Directly smashing the market to ship very little, only when the altcoin season is crazy, is it the best time for each project owner to ship. (Layout is ongoing, communication: BNB226622 welcomes everyone to actively participate and witness the moment of miracle together)
