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 is a good question. I think for me the answer would be yes. Anyone that owns the coins would be considered an investor regardless of how they acquired the coins. Unless you inherit the coins you are spending something to get them, in this case time.
