Bitcoin keeps going down and forecasts of a rebound don't fulfill anymore
Bitcoin will go down when last miner will stop mining it. For Bitcoin to work you only need two users. Where there were Satoshi and Hal Finney, they made it work. Satoshi by himself could not. I mean he could send coins to himself, but that would be just pointless.
That's because blockchain technology is a broader terminlogy and also thing than Bitcoin. Bitcoin is just a part or portion of thousands of cryptocurrency, which is under blockchain technology. If ever Bitcoin will be gone someday, there are other cryptos that could still exist in this industry given how many cryptos are being generated every week. Blockchain technology has its obvious advantages.
No, it seems that many believe this market can keep going without bitcoin, maybe at some point in the future that statement is going to be true but right now that is unimaginable, bitcoin is everything for this market if it were to disappear for some reason you can be sure that all coins will disappear with it and it is not really complicated to understand why, if bitcoin crashed and disappeared I will most likely never invest in any cryptocurrency ever again because if bitcoin could disappear then that means that no coin is safe.
It is not acceptable in present time and similar is the case for future also. You talked about if condition in future, see Bitcoin is the beauty and strength of crypto market and as its value is increasing day by day its strength is also increasing. How can you imagine that such a powerful coin which will gain more attraction in future also can be over?
