Bitcoin remains the dominant cryptocurrency, but its future role is uncertain. Some experts speculate it may primarily serve as a store of value. This assumption stems from the rapid technological advancements in alternative cryptocurrencies (altcoins), many of which now surpass Bitcoin's original blockchain in functionality.
For instance, Ethereum's blockchain processes blocks in seconds—significantly faster than Bitcoin. Meanwhile, IOTA utilizes an entirely different architecture called the Tangle.
