It seems to me that people are now giving more importance to Bitcoin than altcoin. Because there are people in Corona panic all over the world this time. At the moment, very few people will consider investing. Those who invest will first they think Bitcoin is safer. If the Corona Virus 2020 lasts throughout the year, then there is little chance of recovering the altcoin market.
That has always been the case ever since I entered the space years ago. I mean,,, sure, at every random time you have people talking up an alt. Like Ether in 2017. Or BSV even in 2019. Ripple. Whatever coin it was, they had their time, but Bitcoin always held steady no matter what. I think altcoins have to accept their success is dependent forever on Bitcoin.
We can't say forever as we haven't see the future therefore we can't tell.
IIRC, there was a time that bitcoin dropped its dominant rate and bitcoin and altcoins were not too dependent with each other, however that was just a very short time as in general it was really bitcoin who cause the movement of the market with its significant news as people love to speculate on it.
The future is good for bitcoin but I'm hoping its dominant rate will drop a bit so altcoins as a market will also improve its strength.
