To be honest i have no idea as i think that the whole crypto market is extremely hard to predict and i also think that the market can still be manipulated by big whales. At the moment the total market cap according to coinmarketcap.com is 1,27 trillion USD. So i personally think that maybe around 5 trillion at the end of 2025 are possible if the surrounding conditions are positive and in favor of the crypto market. I also think though that it is possible that we stay at the same level as we are now for a few more years. If the federal banks keep on increasing the interests rate again then maybe a lot of  capital will flow back from cryptos to traditional bank products.
