I'm not sure if this is an honest question or just a ploy to try to increase the traffic of a new site which hasn't yet proven itself worthy. I mean, a site offering ads spaces should have one thing: popularity or high volume of traffic. MultiCoinAds doesn't have it. Well, what do you expect from a days-old site?
Why ask, in the first place? If you are planning to put up ads there, the price is dirt cheap. The most expensive is as cheap as 30 Sats per 60 seconds. If you are planning to earn by way of ads clicking or faucet, the minimum withdrawal is also very low, with BTC at 0.00025
BTC.
[1] So, there's really not much to risk from your end and nothing very interesting in this site.
