Of course, because every alt is based off BTC price. If BTC goes to $0 so does every single coin. Until the system changes that is how it will be.
You wrong about that, eth will take the lead in 1 to 3 years, i do not think is time for that yet, but it will be a time where eth will be top cause is a much more complete digitalcoin than anything in the market right now.
Maybe, but in the last 3 months eth/btc ratio dropped from 0.1 to 0.6. Since yeterday altcoins are rallying, but eth seems a poor performer, even etc is outperforming eth, so the value of eth in comparisson to other altcoins is on a downtrend, not the first time this happens, but at his moment eth seems to be weak and that money is betting on other altcoins
