Cryptocurrency bounties are generally simple tasks that a developer of a coin creates for promotion. Once the tasks are completed, the reward is given in the form of the coin created by the developer. These tasks include promotional activities like social media promotion. Bounties are even made use for penetration testing and rewards are given to developers, as well as, ethical hackers to find vulnerabilities and bugs in the product code. 

A crypto bounty is regarded as a fantastic way to promote a brand new crypto asset. They are also perfect for those individuals who do not want to make any kind of investment except their time and still get coins. Depending on the strategy of the company, bounties can be implemented after or before a project's ICO (initial coin offerings). 

Crypto airdrops are a form of marketing campaigns that are used to create awareness about the project. Doing this gives them the opportunity to grow their community and attract more customers. The airdrops are in most cases distributed after the ICO. It is also an easy way to promote a project and build a crypto community. Their main goal is to get users who spread information throughout different social media channels about their projects. Mostly it's about sharing and liking posts on their social media channels. As you can see the tasks are quite easy to fulfill. Because of your support, more people will learn about their projects. This will raise awareness and attract new potential investors. A high user base and awareness have a positive impact on the token value. That's mainly the reason why they are giving you tokens for free - That's the way how they promote their projects! Here are some reasons why companies give away free cryptocurrency.

For an airdrop, you have to do an activity only once. After a while (mainly after the main sale) you will get your free tokens. Rewards are lower, due to lower effort.

For a bounty program, you are asked to do regular activities and you often have to report all tasks which you have done to the project team to receive your tokens. 

Bounty programs are worth more than airdrops, but the effort is not comparable. Please always keep in consideration that some projects can fail. If that's the case you won't receive any tokens for the effort you've done. 

Each airdrop has its requirements. However, most of them are similar. These are the most common requirements that will allow you to participate in most of the crypto airdrops: 

1. An email account: You should also create a new email account specific to airdrops.
2. Social media accounts: Facebook, Twitter, Bitcointalk Forum and Telegram. Vast majority of cryptocurrency airdrops require having a Telegram account. Other social networks and platforms used on occasion include Linkedin, Medium, Vkontakte, Youtube, Reddit, and Discord. These are usually optional tasks and joining can give you more token rewards, but you can skip them if you’re just starting out.
3. An Ethereum wallet that supports the ERC20 Token Standard (https://myetherwallet.com/).
4. A NEO wallet (https://neotracker.io/).

If you are new to crypto we suggest you create your ETH wallet on MyEtherWallet and your NEO wallet on the NEO Website. Make sure you never share your PRIVATE key with anyone (it’s like a password). PUBLIC key (address) is what you can freely share. Be sure to read and save all information provided to you!

We also suggest to make and use only "secondary" or new accounts for all of them to avoid spam on your personal accounts.

Remark: If you have participated in an airdrop, never leave any social media channel before you've received the tokens of the airdrop, otherwise this can lead to disqualification.

Most of the time, Airdrops are safe. However there are also some fake crypto airdrops around. Please be aware and never give your private keys and never send your crypto to someone else in order to receive your crypto airdrop. 

Airdrop distribution dates are different for each airdrop/company. Airdrop signups typically begin once a company starts their ICO (Initial Coin Offering — public fundraising campaign).

Most airdrops are distributed after the completion of the ICO. This prevents the bounty collectors from creating premature price action before the ICO has finished. Sometimes, bounties are distributed weeks or months after an ICO, so if you have a question about a specific coin you should try contacting one of the Admins in their Telegram group. Admins can be found by looking at the group members and finding the ones with the “admin” badge next to their names. You have to wait until all ICO stages end to receive your free crypto airdrop tokens. Don't be surprised if your wallet is still empty for one week after doing airdrops.
