My opinion is that in time Bitcoin market share will keep reducing, as many other coins and tokens and platforms will keep surging.
In the long term, the blockchain technology is very disruptive. Bitcoin will more likely compete with Gold, Ethereum will provide a backbone for many uses.
So I am not really sure a collapse is incoming, it depends if a real bubble will quickly form.
Too fast to mention the bitcoin market is about to collapse, bitcoin is very strong and it is unlikely that bitcoin will collapse quickly. It's just negative thinking that is too panicky with the situation.
The market of Bitcoin is not going to collapse and the reason is its work and function it is responding well to people living in this world for fast transactions and investment with huge profit.
So it will never collapse and this is just a down in the market which will recover soon so be optimistic about the future of Bitcoin. It has recovered in the past and will be recovering and will be improving in the future as we know that the crypto market is improving with the passage of time.
