Many wait for BTC to correct to enter altcoins, but when that happens, dominance may drop, and altcoins may rise, diverging from BTC's movement.

Don't try to hit the exact top of BTC dominance; entering before a dip is confirmed is a common approach, but always with risk management.

Split your capital into stages for gradual entry in case dominance continues to rise before reversing.

A drop in BTC does not always result in a proportional drop in altcoins, as supply and demand, among other factors, can influence their valuations. In some cases, altcoins may even rise while BTC falls.
