If Bitcoin can reach $100,000 , then investors will tend to buy more altcoins and that makes the market have a large stability. Now any predictions are possible and I believe that Bitcoin can achieve this value in the future because I have great faith in this market. Maybe people are afraid of not being able to buy cheap Bitcoin but for me the current price is still very cheap and Bitcoin has always been my top choice.
I would not think towards that direction that much, remember that when bitcoin rises, majority of the altcoins that are with real use case which happens to be the top ones will follow, imagine that bitcoin reaches that amount now, it means that coins like Ethereum would have already be going towards $10,000 too which happens to be the price of bitcoin presently, although at $8k now but I know it is going back to $10k soon.
If people are complaining of bitcoin price too high right now, what will make them not to also complain about altcoins prices too in future when bitcoin reaches $100k, except those low cap altcoins that may not even see bitcoin witness such amount because the more bitcoin gains dominance, the more those other altcoins that are not top coins will go off the market.
