There is no easy money anywhere. The fact that the crypto market becomes more efficient and in this market it is more difficult to earn money has its advantages - the reliability becomes much higher than before.
I agree with you that Bitcoin and cryptocurrency do not have enough stability. Many investors and traders even now do not believe in cryptocurrency and the fact that it is a bubble, but at the same time they are trying to make money on it. It's pretty funny.
At the moment, the crypto has a capitalization of 200 billion dollars. In general, the whole crypto. I think there is no bubble here, you had better look at the stock market in search of one.
