Most altcoins in the secondary market will not have a market trend. The logic is simple: most of the chips of altcoins have already been sold to retail investors, and most project teams themselves do not have the ability to recover their chips.

Therefore, their market control rate is very low, and no market maker is willing to take the initiative to provide liquidity. If they want to do so, they need to buy back the chips.
These projects mostly follow the market fluctuations, with only passive market makers placing orders and rarely actively pushing the price.
Altcoin season only appears in altcoins with high market control rates.
So, how to determine if the control rate is high or low? It's very simple: new projects listed tend to have high control rates, and there are two situations here.
1. Projects listed on bn spot with decent liquidity, where the project team mainly focuses on selling chips and does not seek active market makers to help realize market value. Generally, this is the case, though some wealthy project teams may be an exception.
2. Projects listed on Alpha＋ contracts, where they want to sell on Alpha but lack sufficient liquidity and cannot sell out. They want to make money on the contracts but lack the expertise. So, they can only cooperate with active market makers to help sell and potentially make a big profit during a market move.
In summary: Altcoin season only occurs in high-control projects within Alpha＋ contracts. Others are very difficult or require time to accumulate, and some project teams need to buy back their chips before they can play.
