I just started with buying some crypto coins and have a lot to learn.
But almost every time when Bitcoin is up, al lot of the other coins also go up. And the moment Bitcoin drops , the other coins also drop. Is this just a coincidence or is htis how it always works? Can someone explain this to me?
It is a good thing that you are venturing on the altcoins part of the crypto world. Great decision.
Now, about your question. You see, this isn't always the case man, there are some times that when the bitcoin's price is down, the altcoin's prices goes up and vice versa. This can be due to convertion of bitcoins to alts and vice versa or taking profits.
And sometimes, the prices of altcoins and Bitcoins rise and fall together. This is because bitcoin's price influences the price of altcoins since this is what we use mostly to convert cryptos to fiat. So when whales takes profit, the price of bitcoin goes down which triggers panic sellers and this makes the domino effect. That is how i see the crypto world.
I hope this helps you in any way.
Good luck and welcome.
