However, I am not sure you will have the time to manage this campaign and also run your business. This forum will demand your attention even undully, that is why it is recommended to hire someone else to manage this campaign so that you will buy time for yourself and understand how here works.
Yes, you are right, or he can work with a manager and ask for advice for a fee. I don't want to judge him this early, but I hope he is aware of what happened to Cryptomus, The community can help him with his campaign with our advice and other help, as any casino that wants to launch a campaign here is very welcome and supported by the community.
I hope he learns a the long way on how to properly manage his campaign to maximize his casino's exposure.
Actually it is fine for any project to run a campaign themselves without a manager especially if they have low marketing funds so managing the campaign themselves will save some money.
Of course having a well known experienced will be better, but maybe if this casino do not have good marketing funds and they want to run it themselves, maybe better to have an escrow to keep the campaign funds so all participants are guaranteed of payment.
Lets just see how it goes and maybe they will evaluate it after a week or two, if they think that it does not work as what they expect then they may consider to have a manager to make it better.
