I won't click any link that I'm not familiar with though it's just an article you should quote some of those important part like the 6 ways of earning tokens. With what I know here are some of ways to earn tokens.
- Join bounty campaigns (signature,article,telegram,social media, blogging and etc.)
- Airdrops
- Work and get paid with tokens
- Trade your other coins
- Faucets
That is what everyone familiar with and more profit is with joining bounty campaign. These ways can learn through reading and experience and choose which is the best. Almost of them can do on one coin. Join bounty and receive rewards for your work then you can trade the coin, easy as that. Airdrops and faucet are same thing but has not work all the time.
