Will Altcoins survive as bitcoin is going higher and higher and the demand is getting increasing every day, what will happens to altcoins
Of course, as long as they are very useful in and have a demand. But most of them in my opinion are shitcoins made just for profit with similar uses so I don't see most of them going to survive for long.
Currently, as far as I know, most of new cryptocurrencies all are the token from ICO.
I do not think ICOs token and altcoin are same concept, because ICOs token do not have decentralized and created by someone or force and it looks like the stock more than the altcoin.
They are not all erc20 tokens of ethereum. Some projects are blockchain projects and they have their own blockchains. Some of them are in form of erc20 but in the future they will create their blockchains as well.
