These are uncertain times, the cash flow can sometimes be positive and sometimes negative, due to changing market conditions, the Federal Reserve's policy, tariffs in the US, some indicate that the bullish season for altcoins is just about to start, but sometimes there are crashes in the coins that keep one alert and cautious. The trend indicators are sometimes uncertain, sometimes a green signal is accompanied by a sudden drop, and sometimes a red signal means nothing because the coin can recover quickly. One thing I have been able to observe is that many coins are closely linked in trend with $BTC , like $SOL , $BNB , $XRP and many others, and more and more are joining this list, it is like in the movie The Lord of the Rings, one ring that controls the other rings of the elves, dwarves, and men. The coins that are not linked to BTC have the disadvantage of being highly volatile and unstable.
