The Bitcoin dominance is not a problem.
There is an intense competition in the crypto environment, and Bitcoin shows its strength as the first and most popular cryptocurrency.
When more and more coins are created and become popular, the Bitcoin dominance will eventually disappear.
There are already many popular cryptocurrencies in the market with real use cases.
Still, they struggle to increase their market share and Bitcoin continues to dominate the market.
If altcoins didn't show that they are alive and investors start to trust them, we are going to have a problem as the market will collapse.
