This market is not attracting that many investors: Institutional money will not enter the market for a long time, many retail investors are leaving and some are entering the market. This market can not grow because there are not enough investors. BTC is in peril because when people buy in other pairs there will be no need to buy it: exchanges will make it easier to buy in using a usd token and then use that to buy alts and BTC will NOT BE THE RESERVE CRYPTO.
you are looking at things in a very pessimistic way, and it is true that we need institutional investors, but you should see that institutional investors will only come in when the regulations are very clear and banks are not creating barriers for the people they want buy bitcoin. If many banks and governments and even companies like Visa and Mastercard were not creating many obstacles for people using bitcoin, then today the price of bitcoin would be much higher and we would have many more investors entering the crypto world
BTC will die a slow death because of this.
bitcoin will survive, do not be too pessimistic
ETH will not suffer from this because many platforms are built on it. No platforms are built on BTC.
So you're campaigning to btc die and ETH survive? this is your true intention
Example: An entity buys an ALT and then pumps bitcoin. The Alt goes up and they sell the ALT at a profit and then they dump the bitcoin. This is one example. These guys are professionals and can do this any tick of the clock and it is so so so unpredictable.
Many people buy first BTC and with BTC buy altcoins and sell these altcoins to have more btc and hold btc. BTC is the priority for people and altcoins are a means to get more BTC
