Thank you for advice. But how do we start if there are lots of bounties are just scamming us. In fact, even I combined my work hard to work smart, nothing happens. I am still poor today. I always look at my wallet and saying that this will have a few bitcoin soon. But whatever I did, there is always a fail. I don't know but I think crypto is not my industry because I have been there since 2017 and till now, I did not gain a lot.
