Bitcoin can indeed be used as a crypto market signal where when the price drops it will also affect Altcoins, although there are some altcoins that are not affected by Bitcoin until now Bitcoin is still a benchmark for other coins and a reference in the crypto market. The market is indeed confusing because we never know for sure when it's time to go up and down so we have to really understand and analyze the market. To respond to market situations that sometimes go up and down, we need to be patient and careful because if we rush and panic, it will make our minds even more confused, and can end up getting losses.
Because the movement of the crypto market is based on supply and demand, therefore it is difficult to predict and sometimes looks confusing.
Supposedly if we study crypto properly, we should not be confused. Because as long as the choice of coins for investment is correct, then we just
need to be patient to be able to generate profits. Regarding Bitcoin price movement what you say is true, Bitcoin price movements can be a sign of
where the market will move, because most of the altcoins movement is strongly influenced by the movement of Bitcoin. As of now Bitcoin is rising
to a price of $42k, then we can see on the CMC site, almost most of the altcoins have also gone up in price. Hopefully the price of Bitcoin continues
to rise and can return to the ATH price, then we can see the bull market coming.
