The altcoin bounty does not produce as imagined. Newbie won't be able to make thousands of dollars from bounty whose only job is spamming social media. I don't think he should because in the end the time and the income won't be worth it.
It was better for him to hunt for knowledge than to hunt for money since a beginner, it was a good option to consider. For example, he can learn how to manage and develop a website, if successful then becoming a user spreading affiliates from various sites will also benefit.
Not only altcoin bounties but many more. If you really want to get thousands of dollars Bounty altcoins will not be able to give it. Signatures can also be a great option, but they also need to be good at developing accounts and contributing to forums. Hunting for knowledge since beginners is a good thing, but it must also be adjusted to our basic abilities whether we can do it or not. Don't be too pushy, while in the learning period, you can do some airdrop, tesnet, etc. tasks.
