BTC influence

[labilaab]

This keeps me wondering everytime I open Coinmarketcap if btc goes down the following altcoins go red too but not all. Are all altcoins mostly directly proportional to Bitcoins pricerun? Is bitcoin have that so much affect on them?
Other altcoins I observe that is not affected are those with only low total supply.
On your own opinion?

It is undeniable that altcoin always follows the movement of bitcoin because bitcoin has great trust from investors. According to my analysis, if there is a sign of bitcoin rising, investor confidence in crypto will increase. This is what causes the altcoin value to increase.

You are not the only one. I have seen this question posted many times already in various forums.

It should not but it appears to be directly proportional since most traders behavior make it happen.

Maybe you mean those with low volume and not supply. Also those that reached their lowest point.
