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
Every individual who holds a number of coins can be called an investor. and some prize hunters save campaign prize coins as their future investment. That is why in projects that ask you to confirm your identity, not only do investors need to go through this process but prize hunters too, and that makes sense because they get a share of coins and dividends that might, if any, the difference is that investors enter money into the project while the prize hunter puts their effort and time.
