I normally see some crypto projects which promise Investors certain amount of dividend depending on how much coin/token they own.
The word "Investors" is normally used for people who own shares of a particular project/company, but in cryptocurrency this "shares" normally refers to coins/tokens, which makes me wonder if bounty/airdrop hunters are also considered "Investors" since they hold certain quantity of these coins/token
This can go in a lot of ways... They may not be outrightly investors because they didn't buy the tokens, but they are still investors because they worked for the project. Just like the team and the devs, they all still did invest and hence can be investors..
Talking about the shares, it depends on how the projects wants to the share, there are some projects who pay some dividends for all holders of the tokens, this way, every holder get the share, doesn't matter how they got the token..
So, technically, bounty hunters are also investors.
