I dont think so. Bitcoin is the foundation of this market so why you want to see it being thrown away from its own habitat? You think of your own coin that can compete against bitcoin but you are going far beyond thinking and you all want to kick bitcoin. The market will collapse of you are pushing bitcoin away from its ecosystem.
Rightfully mate,bitcoin cannot be replaced by the coins circulating in the market,yes ethereum is a good coin with a good platform but this is not enough tl break what bitclin stablished over the years of existence,if this thing would possibly happen this is not the right time,in future or maybe five to ten years from now,well no one really know
Bitcoin is the center stage of the crypto ecosystem and it's hard to beat this out by just asking that there's a potential altcoin that can replace it.
Everyone must be optimistic about bitcoin, you have never read about it being the starter of this market. It's impossible that it will be overthrown by any altcoin that you bet out there.
But remember the banker said that bitcoin is not enough scalable to be used as payment system (similar to the money) That means bitcoin becomes a good thing to store our value and to be used as non regular transaction in our daily life. I just try talk about the fact about bitcoin.
