Obviously this will happen in a gradual way, but I do not believe that bitcoin can retain its current dominance for more than ten years before starting to fall into disuse, although perhaps its influence could persist in the market about ten years.
In the end, bitcoin is likely to subsist for many years, but by then it will have evolved in such a way that it will be virtually unrecognizable for today’s standards, and in fact it is difficult that in 15 years there is something similar to the current cryptocurrencies before the spectacular advances in digital technology that are approaching.
Like others technology, bitcoin is the product of technology. But for many people, bitcoin is store of value and digital gold. Maybe many new coin with new technology and new features, but i am believe bitcoin remain the first choice investment in cryptomarket
