"There is no free lunch".
there is mate . free exist on this world but not going to work forever or permanently .
No one will pay you free even you see their ads but in return they pay you not even 1%.
but atleast they pay . ads is popular right now , we as a visitor see ads or click on it and owner pay us small . small because its not a hard work .
The best way to earn in passively is Trading and writing blogs abut the crypto. Signature campaign and joning airdrops also best way to earn coins and that coins convert in BITCOIN.
trading can work passive because you can use bots but writing , sig campaigns and others that you mention were are active jobs .
I would suggest to new comers dont be disappointed just stay at forum and learn about the crypto market and improve skills and find a way where you feel that you are good at either Trading,Airdrops,or investing.Avoid false and scam airdrops which will just waste your time and energy.
thats a nice advice mate . hanging out on this forum can give them learnings that they can use later on to become profitable .
