When bitcoin is pumping, altcoins prices will decrease. Moreover, when Bitcoin is dumped, the altcoins prices will go further down.
If you learn the current trend in crypto prices, most altcoins follow the Bitcoin price. If Bitcoin price increases, most altcoins will increase their prices as well. This may be different if we are already in the bullrun season, the trend may change because people's focus will be different.
And when the price of Bitcoin consolidated after all this, then there is an altcoin season.
For altcoins season, it should be in the bullrun season, we can't expect it happens in the near future. Currently, if Bitcoin price is hard to increase, most altcoins are also a bit slow to increase their values. But it is for common altcoins, it is different on hype coins. There are some coins which rely on the hype, they don't depend on Bitcoin price trend.
