there are 2 ways if you wanna get some free token or coin. First, you join the bounty campaign and do some task, the easy one is social media campaign, but if you wanna huge result you can try translation or signature campaign. The second way you join airdrop, but airdrop usually doesn't give a significant result. And please remember, both of them need time before you can get your rewards.
Payments can be delayed for months.I participated in the bounty campaign and the project postponed the ico until better times.With this option, the payment can not wait.
