Can you still make money in the crypto world?

Yes.

The crypto world is the only market that provides you with an API with zero barriers to entry. Currently, there is still a lot of excess in the crypto world, but visible alpha is becoming increasingly difficult to obtain. If you have experience in quantitative trading, you know that there was a significant alpha decay in 2022, and it has only recently started to improve. This thing follows the U.S. stock market; when the U.S. stock market goes up, the crypto market goes up too.

The current situation is that there are still many excess returns in small cryptocurrencies, while large cryptocurrencies are more competitive. ETH is much easier to trade than BTC. For small investors, the crypto world is still quite profitable.
