Actually Bitcoin price often influence altcoin price but there's a season where altcoin do extremely well even when Bitcoin is stagnant or declining. What if this season comes More often, what will be the faith of Bitcoin?
Rather what will be the faith of altcoins if bitcoin remains stagnant? Altcoins should be more grateful that bitcoin still has value and still hold its ground than any other coin in the crypto market, or else most of the altcoins if not all could have crumbled today. No matter how many times this season comes (it is called altcoin season), it will not have anything to do with bitcoin position and nothing will happen to bitcoin and will continue to progress has it has been for a long time now.
