It is reasonable to say that Bitcoin's (BTC Dominance) acquisition has entered a phase of continuous rise, since the beginning of the institutional and international trend towards it, specifically after the listing of ETF funds that granted Bitcoin financial legitimacy on a global level.
Based on this, yes, it is likely that in the coming years we will see it fluctuate within a high range that may reach 90%.
But does this mean the end of altcoins?
The answer: No.
Altcoins will continue to represent a halal financial leverage for Bitcoin and a means of hedging and investment within the market. As market liquidity is estimated to reach tens of trillions of dollars, a simple movement in Bitcoin's dominance of just 0.01% will have a clear impact.
Moreover, a decline in dominance of just 0.5% may be enough to push altcoins towards a rise exceeding 100%.
However, you must realize that your profit at this stage or in the coming years will depend entirely on your entry point, and the price and timing of your purchase.
It is true that some coins will disappear and others will emerge, but Bitcoin will remain the most prominent and central asset in the ecosystem.
To clarify:
Bitcoin's rise from $1 to $100,000 means a growth of 10 million percent.
As for its rise [the same $100,000], from $1 million to $1 million and $100,000, it does not exceed 10% only.
