Yeah, it is 9 million per month, but you also need to understand two things;
-The advertiser is not interested in having bitcoin, they want to pay for their ad space and that's it.
-The site takes those bitcoins, but also doesn't want to keep it, but rather exchange it for fiat asap.
I'm not saying these news are not good, because they are, they are promoting bitcoin and showing how it can be used where other payment methods are failing,but
to think or claim how this will bring bitcoin itself 9 million per month influx just because the trading in that amount will happen is not true. The price shouldn't be affected much imho.
cheers
influx is the wrong word. It's about liquidity, which should help Bitcoin to stabilize the price.
