There are plenty of crypto bounties if you don't mind the concept. All you have to do is create a few social media accounts with at least a couple hundred followers and a few Blogspot or comparable sites.
The most straightforward technique is to airdrop tokens to holders of a different cryptocurrency. This airdrop is ineffective, and it's now known as "token spam." If you have an ETH address, there's a good chance you've got some unknown tokens on it visible on ethscan.io that you didn't know about. That's token spam.
