Maybe or maybe not.Crypto market is very unpredictable.So we can't say what will exactly happen in the future.Many coin's are available in the market but still Bitcoin is dominant of all.We are observing that many coin's are growing on a decent rate so maybe in future some other coin overpower Bitcoin. But I feel that it will never happen. Bitcoin will always be the dominant one.
We should not speak with doubtful ideas about the Bitcoin and its future along with its competition. For sure Bitcoin has such place that is making it irrelevant that we compare it with other cryptocurrencies. The place of Bitcoin is firm and it is known as base currency so this will be the future dominant coin as well for this we can see the increase in number of participants for it.
