Im a N00b. I noticed that most of the top altcoins price went down when btc price went down. I bought some bitcoins so i can buy some NEM. I was wondering if I should wait a little while for the price of btc to go back up or would that mean that NEM prices would most likely go up too?
All this altcoins are depending in the Bitcoin's price generally. Bitcoin is the first and the most used , and the most valuable crypto currency ever, so it is normal that all the other crypto currencies values get affected by the bitcoin's price chart, either going up or down.
i think it will be different if the altcoin is compared to the fiat price in the market, for example etherum / USD, although bitcoin price rises does not mean the price of etherum to the dollar will decrease, i think it will depend on the exchange rate you will choose, because it is very possible when bitcoin prices fall instead of etherum strengthened in dollar, not always affected by bitcoin rate
