I earn altcoins because of airdrops and bounties. Airdrop is the popular method to earn free coins. Bounties are popular too but are some bounties are not paying. But for me, go for airdrops or else invest for the best coins.

I receive my rewards on bounty. It depends on their reward! Sometimes it cost 10$ sometimes 5$ but i think it depends on your quality posts.

Yep! Airdrop is worth it to spend some couple of time because you can earn tokens or coins for free.

First of all my friend just invite me to join cryptoworld since november 24, 2017 and this account I just created november 25, 2017 but i can't open it due to proxyban but anyways... I join cryptoworld because I know that these digital money could replaced the paper money someday. Bitcoin just changed my life I thought this is not legit but when i found out I join airdrop and i earn money I told myself to proceed on these journey and make my family proud someday. That's why I join Crypto but thanks to my friend without him, my life would not changed.
