for the time being the price of ALT will be difficult to increase because the price of BTC is still stable and its dominance is still too large.
so we can not conclude that ALT is now rising, it is actually getting worse.
the only way if ALT wants to go up is when BTC dominance decreases from 50%.
You can't determine effect from the conclusion. You are saying ALT will go up when BTC dominance will decrease below 50%. That doesn't mean anything. BTC Dominance below 50% is conclusion, not effect.
So for both alt coins to go up and btc dominance to come below 50%, we need some market movements.
