I participated in many programs, but nothing came to my wallet
That's rather unfortunate. Because I also did a lot of airdrop, but still received some payments. However in real them to bring and it didn't turn out. Because the token was not released to the exchange and offered to use the token within the network as a payment for their services.
I have followed airdrop, but until now I have not received anything even though the project from the airdrop I have followed has been completed but many of them did not pay participants and the paying airdrop only gave me some coins that were very cheap and I could not sell because not worth the fee
