Altcoins only follow the price movement of Bitcoin, if Bitcoin pumps like now which reaches $ 31k altcoins also experience pumps,
and even some altcoins such as SRM, Poly, Waves go up 50% more, if you want to see the situation from altcoins,
of course the first thing we see is the price Bitcoin, so be careful when buying altcoins during a bitcoin price dump.
thats it, the rule of thumbs in determining in which direction these altcoins will go could be foreseen simply just seeing the trend that bitcoin currently be having.
though sometimes altcoin didn't necessarily follows the trend, but we know the general idea of how the market sentiment currently is.
so if anyone really eager to invest then they should determine the sentiment towards the market and general trend so that they didn't make some really bad decision.
and after that losing some of their investment. knowing what most people currently interested in is the key.
That's how it is because until now Bitcoin is still the king of crypto and it is also a benchmark for altcoins,
it is important to keep abreast of market movements and with that at least it will help us in making decisions,
simply we need to know when to sell and buy.
