The market will always follow what bitcoin does since it's the main pairing to all alts. Etherium is nice but it doesnt have as much volume as Bitcoin has.
OH, you want to buy some xrp? gotta buy bitcoin first. Oh, you want to buy some trx? gotta buy some bitcoin first. etc.
And everytime you sell bitcoin into ur altcoin, theres also a buyer who just sold his altcoin for ur bitcoin.
So if you want to break away from bitcoin in prices, you have to make more etheriums, more neos, more vens so ppl have more options to buy their altcoins.
Or better yet, pair them with USD, formerly USDT, but we see how that went.
As you are saying, it means that if the BTC rises, the coin altcoins will go down. BTC going down then the altcoins will be increased?
