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?
The price movement of Ethereum is as unpredictable as bitcoin. Over the years, ethereum managed to stay the closest to bitcoin so there's a high probability that if bitcoin's value were to reach a very high value at 2030, Ethereum might get that $100k prediction you are giving. We never know how high bitcoin might get on the next few years or it may also get low if we get unfortunate. Nevertheless, bitcoin and ethereum's capability of reaching a high value is very high next few yours so we should manage our investments on it and prepare on the wonderful future it offers.
