The main thing is how one can earn if he invests in Bitcoin and if he stays for a long time.
For those who understand the essence of investment, of course it is easy for them to understand and the results they get, everywhere the nature of investment is to buy when it is cheap and resell it when prices soar high, This applies to all aspects that have an investment nature, for example: Bitcoin, gold, property, land and so on.
The same goes for Bitcoin investment, especially in the long term method, for example if you buy at $20k and sell at $30k, you will automatically see a profit of $10k, and so on, so the income you get from crypto investment depends on how much value you invest, the greater the investment value, the greater the income you get.
