Bitcoin created first or Binance exchange created first? and if I remember correctly, binance has only been around since 2017 and before that we also had many other centralized exchanges. All of them have a lifespan and are always replaced by other exchanges from time to time. So there is no reason that when binance dies the cryptocurrency will also disappear, but if bitcoin dies there is a high probability that the market and exchanges will be gone.

Binance or tether or any other company or project is just a part of this market, so without them there would be another product to replace them.

By the way, this was the first bitcoin exchange, at that time with 1 dollar we could buy thousands of bitcoins .
