I think it can be a good decision not to do bounties. It has pros and cons of course, but at least there won't be the usual bounty dumpers.
I guess that is because they have other marketing campaings in mind. Maybe they don't have enough money for everything and had to make a choice.
so this project will not you have a bounty campaign? perhaps they have in mind other methods to promote, advertise the ico...
It's unusual and unique decision but they will prevent bounty dumping just after ico
Now many ICO projects have bounty program - however, as practice shows, not all of them succeed. I think SophiaTX team has alternative solution for marketing, or they are confident in their abilities.
