Since most of the alt coins are traded with BTC or ETH. SO I think altcoins prie are dependent on the price of this two.
What is your opinion please share.
that's not true, but it's not wrong.
altcoin's price just depends on the price of BTC, but if it is pumped, it won't need to care about BTC. if it is in the process of consolidating, when BTC increases its price, there will be a difference in exchange rate, altcoin will be strongly reduced.
