I believe that in the event that bitcoin will be dead, definitely I would say there will be a big negative impact in the crypto market since btc is always the baseline in every market movement since btc and alts are correlated with the other. However, in my opinion, there is no possibility for btc to die in the current scenario since btc is doing good performance in the market and it is still getting better and better and more and more people are supporting btc.
Bitcoin don't die, and with no reason the death of crypto mania. Look at the chart guys. Market is Volatile, any thing can happened at any given time, price market value may goes up and goes down, dependent on the market investment for Bitcoin, the market structure is Stable, with good fundamentals, high level of confidence of the investors of Bitcoin. I am very optimistic with the current trend of the Market, Bitcoin will make a Bull run anytime soon.
