I see some crazy numbers being thrown around, one is an Ethereum coin going to 100k in 2030. How can you tell if a price prediction is too high in relation to market cap? Some people say some coins cannot hit a certain market cap. How can you tell if a market cap value is too much for a certain coin? I understand that there are coins where there are great number of circulating supply, but why can't they reach trillions in market cap?
Because Bitcoin's max supply is limited to 21 million, for example. But Ethereum's is unlimited. That is a big hindrance for Ethereum to reach sky-high levels. But we never know certainly whether Ethereum can reach $100k in the future. Let's say that it reached, then Bitcoin price will most likely be many times more.
