My Question is that people say 90% of altcoins will die, If there are 1500 altcoins then 90% is big number, But i've never seen a coin die unless it was a scam or something, even Bitconnect is still alive, How will the Altcoins die? Is it even possible?
I would say emphatically that bitconnect is already dead and everyone knows that. That a coin is still being seen or on an exchange, does not indicate that it is alive.
You need to even check coinmarketcap. It has no marketcap, no volume, no exchange is even mentioned in its respect.
You should then know what that means.
