ICOs already have IBOs very often to promote themselves. It's happening right here on Bitcointalk too, having ICOs throw around with millions of dollars for their IBOs. These IBOs often includes Signature campaigns, article writing, translations, social media promotions, etc!
However, an initial bounty offering using purely bounties and no sale is interesting, though I'm kinda sceptical about how they'd make their money... Projects still need money, even when a lot of human work is provided to them...
These articles lack readily available information about that.
When you can essentially crowd source time, what do you need money for? I don't think this would be in lieu of other fundraising methods. If you have a supplier who will only accept cash, someone could provide cash for "equity". No?
Crowd source time? I think you lack a bit of knowledge about how cryptos work...
I hope you do know that Cryptocurrencies are built on a ton of code?
For the ton of code, you need developers.
For developers, you need money, which you could get through having them pay themselves by entering the bounty campaign and obtaining tokens, but what about the organisation of it all?
After all, someone must be on top, making sure everyone who works well gets paid. What does this person want? Money. Where is that money coming from? No idea. Maybe he pays himself a bounty, but who's controlling that? How much would he get?
Sure, it's possible to avoid the involvement of money completely, but it's not quite as easy as it may seem and these articles lack details about how it'd work. It looks like it's made for the newbies to read, so they join it and get in to cryptos, etc.
