this is the obvious reason why most altcoins are called shitcoin.
You as campaign manager probably know what altcoin teams ask from you, usually bumps, spreading a nice word about projects etc... often and without cover and the actual product behind.
to be honest, I myself had a lot of failures while believing in altcoin projects.
at one point I had altcoin worth 7-9 in BTC, now that I would try to turn that same amount of altcoin into BTC, it wouldn't be enough for either 0.1Bitcoin. Plus, many of these projects are dead now even if they sound very perspective and they had great support.
I think only the top 10 ^{maybe 20 from} on CMC are worth being considered as trustable and to hold.
