If comparing bitcoin and altcoins, bitcoin is still the best in every way. But in terms of volatility, bitcoin is gradually more stable than altcoins, and that is why many newbies are not interested in bitcoin, and they rush into altcoins in search of bigger profits. But the way I see it, people who invest in altcoins after a while will also return to bitcoin because investing in altcoins is not as profitable as they think.
Broadly speaking it is so, Bitcoin Votality will gradually stabilize, but seeing how stable Bitcoin is depends on how market demand is.
Bitcoin's volatility will also rise and be more aggressive so that bitcoin market movements become more active.
As will happen in Halving, this will make Bitcoin's volatility increase
When Bitcoin has shown a decline in dominance, and volatility is quite stable it is an opportunity for Altcoin to party.
Loss or profit in altcoins depends on how each person trades and what altcoin they choose, it will greatly affect.

The easiest thing that affects Bitcoin (or alts) volatility is news, nothing else. Any impactful news, whether positive or negative will effect direction immediately it's released. It doesn't matter where price was headed before. Bitcoin is more fundamental than technical analysis.
This is included in Fundamental Analysis, the market is affected by some news that appears either a trend for FOMO or FUD that is deliberately raised.
Technical and Fundamental analysis both have continuity, in time it will synchronize.
It also looks at the history of bitcoin travel, usually some FUD that appears is always repeated every year or every increase in Bitcoin that will reach the highest price.
