If Bitcoin reaches $150,000 and its market dominance falls to 50%, the total cryptocurrency market cap could reach $6 trillion, with approximately $3 trillion allocated to altcoins and stablecoins combined.
"Leading forecasters have BTC reaching $150 to $200,000 or more at the peak of its current run. If we take the lower end of that band, $150,000, that gives us a BTC market cap of $3 trillion. Now, if dominance hits around 50% as it would in the scenario we considered before, total would be roughly $6 trillion. Subtracting BTC from that leaves another $3 trillion for altcoins and stables combined."
