Bitcoin has been the dominant cryptocurrency for long now, I think that could change in the future. For the market to grow large and compete with global market, its becoming clear that other cryptocurrencies might rise to compete with the Bitcoin's marketcap. Top players from the traditional market need to get involved in cryptocurrency and issue decentralized products, the space need a lot of attention at this time. Such close competition could be setting the stage for a multi trillion crypto market.
There was a moment in the past when Bitcoin's market share was 37.8% and Ethereum's share was 31.1%. Now Bitcoin stabilized at 60-65% dominance, major altcoins struggle to keep up with its price gains and lesser shitcoins are disappearing. With this trend, alts have no chance to dethrone Bitcoin. Some major fundamental breakthrough would be needed, but how can you be sure that Bitcoin won't be the coin to have it?
As for traditional market players, they are into crypto purely speculatively. Even if we are getting more insitutional investors, we are not getting any payment method adoption from larger companies.
I also agreed that crypto need a lot of attention for the market to grow large but not by altcoins dethrone Bitcoin which every crypto enthusiast knew it wont happen though and BTC dominant increase after bitcoin was unable to take down by the government, it literally gains additional attention by investors and it experienced an increase from 37.8% to 62.0%. However, BTC dominant or decentralization level wasnt hinder the market positive change but it the government attitude towards crypto that hindered adoption from large companies and if the government attitude changes now, in a single hour crypto market cap will reach a trillion USD.
