If not for the reputation that Bitcoin has built over the years as a store of value, memecoins scams would have dragged crypto reputation into the mud. Memecoins are no different from Ponzi schemes, left for then alone cryptocurrency would have collapsed. But thanks to Bitcoin reputable, the name cryptocurrency still holds value.
Yes bitcoin is indirectly the reason why altcoins are surviving in the market. People look at how bitcoin price went from $0 to $100k over the last 10 years plus and they want the same result by investing in shitcoins. It’s ridiculous but it’s the truth. Shitcoins are still popular because of human greed, people just want to get rich overnight.
And I don't think altcoin will survive without bitcoin, and when it comes to the market, all attention will be on bitcoin, and when it comes to the market, they are always advising people to invest in bitcoin. And the reason why some people don't want to invest in Bitcoin is because of the price, and that is why people are going for the one they can afford, because when it comes to investment, people prefer to go for quantity. And the majority of them are getting lucky when it comes to investing in shitcoins, and they feel they will make fast money when it comes to shitcoins and memes, but everyone has their choice if they want to invest or not.
