However, in order for many people to know the IEO, there are still some IEOs opening bounty campaigns to advertise to more people, before the IEO is officially sold.
There's a lot of them especially if they are not in big exchange like Binance.
I know
https://coinmarketcap.com/currencies/harmony/ had a bounty while it's in Binance IEO, that's pretty rare and it's also a sold out coin.
So I'm saying it's possible, but pretty rate.
But look at where harmony is heading now, they are going now because the rise was just brought by a hype and they need to bring that hype back again by running a bounty if possible.
It is also a bad idea.
Not at all.
