With every new token circulating in the market, they should add up some value and have their own share of total dominance by price.
But for some years, we are having an increasing number of new coins and tokens being traded but still bitcoin is increasing it's dominance.
According to coinmarketcap, bitcoin now holds a 42% dominance. i.e. the 42% of total capitalization of cryptocurrencies is that of bitcoin.
How is it possible? Are altcoins failing?
The strong bitcoin to this day shows bitcoin that has a larger number of followers than any other coin. They do not buy or sell in a hurry but are holding back or just planning it. Bitcon currently has a more mature market and most of the coins held by traders and funds are abundant. This will happen in the next few years.
