Bitcoin will still remain at its position. A lot of investors prefer to invest in Bitcoin and that's why it is more dominant in the market than other cryptocurrencies. Lots of market predictions I have seen are always favoring Bitcoin for a long term investment. That's why I have invested so much money in it. When the next bull run comes, most of these altcoins will be nowhere to be seen, as Bitcoin will occupy much of the space and more of these altcoins will only be decreasing in price and nothing more. If there are coins that will increase, it will only be the top altcoins with a huge market cap.

It seems to me like altcoins are losing theirs to Ethereum. Just a few altcoins has been doing good as of recent, like BNB. Ethereum keeps growing in market cap and others keeps on losing. Bitcoin retains the 67.7% market dominance. Ethereum is way below, though I just saw a comment here that within five weeks it will be up and close to BTC. I don't believe such is going to happen. But if it does happen, then it's really going to affect Bitcoin, because a lot of investors will switch.
