To run ICO/IEO simultaneously, i think is better. Why hunters are doing the advert, ICO/IEO will be going on the same time. Most investors get to know the project through hunters.
Absolutely true, it's best to run both token sale and bounty simultaneously. For instance, investors still considering to invest in a project doing bounty might come across an article (from a hunter) which explains the project or maybe SWAD analysis, hence giving investors a better insight on the project. If the IEO will be held on top exchanges like Binance, then doing a bounty prior to the IEO won't be a bad idea also.
