I have seen a lot of threads here asking about whether people will invest in a coin or do bounty. Its high time we all understood that, investment is not only about money. To me, any effort put into something to make it a reality can be regarded as investment. People who buy coins invest with their monies whiles those who participate in bounties also invest with their time and energy. Money is a replaceable resource but time can never replaced. To me, bounty hunters are also investors. What do you think?
Generally, you don't have to spend your money directly into a bounty campaign, however your time is still on the table, a good thing is that bounties generally take a little amount of time to complete, so you won'r be losing that much if ever the project ends up as an scam.
