for me , I earn altcoin with airdrop and bounty, because now my focus only on cryptocurrency so every day I have a lot more time for learning, searching and reading about altcoin that has a great prospect in the future, if you want to get altcoin fast the only way is trading or invest in ICO project, but if u want to get altcoin for free, all you need is patience and diligence to participate in bounty campaign or airdrop campaign.
