Yes, I already took a look at them and they have good advice. After reading some tips, I am looking for a kind of a freelancer website which offers crypto payments.
You can also consider finding a freelance work that also pays in fiat.
Used your earned money there to buy crypto.
That isn't much difference in what you are looking for which is earning BTC online and not with the hard-earned money. Generally, you need to work whatever the payment is. Why did I suggest this way? Because in general, there are lots of freelance works that pay in fiat compare to crypto so you need to consider that way instead rather than focusing too much on finding crypto payments.
