My advise to you on the last question is to work hard and earn merits. when you have enough merits. move to the service sections to join bounty payments that pays in ethereum and bitcoins. this the only sure way to earn a penny here. do not listen or join any airdrop activities here because it is a business for some scam people.
Yes, some airdrops didnt have value at all, and i ever got scammed too..
Anyway thank for advice, sir.
For me i will slowly to increases activity as long merit to join bounty payment as you explain...
