can such things attract more people into bitcoins on cryptos at all? i think that a good advertisement for it

I think it will attract more people willing to invest in Coinbase itself rather than Bitcoin. But it is definitely nice to see that a Bitcoin related company made it to this list.

Nasdaq traders will just see the huge sign and ignore

Wow, what great news! This definitely a good thing for bitcoin, it makes the idea of using bitcoin more "common place" and less associated with crime and gambling (a completely inaccurate but real stereotype.) It also helps people in the US recognize a domestic company that deals in this industry/currency/investment.

It's a good sign of things to come (as long as the hard fork does fuck things up.)

thats if they go public at the current state is still hasn't been a year since their last Venture capital investment so maybe in a few years it could happen.

Yea, That is the real irony .... People associate anything with coins, to physical coins... If they look at the name, they might think it has something to do with people trading in physical coins.

In some curious people, it could spark their curiousity and they will investigate further... The competitors on that list, will also look at these companies and they will acknowledge it's existance.

The more Bitcoin companies become visible in the market, the better for the whole community. Coinbase deserve their spot in the limelight, because they are working hard to build a brand. 

Nice! Nothing like a little Times Square exposure!

Every time is the right time to introduce innovation.

I don't think that flashing Coinbase's name on Wall Street would make that much effect on bitcoin's side. However, Coinbase is mainly known because of its bitcoin-related services. Though that means something, we could not easily assume that there will be an effect in price, but we can safely say that awareness about bitcoin was spread because of that advertisement.

Do not lose your power, I believe Bitcoin will going up again.
A thing not effect quickly, it would take an effect later.

True but not quite. Bitcoin users don't care THAT much about Coinbase. But many businesses who want to incorporate Bitcoin payments into their system look at Coinbase or Bitpay as their doorway into the ecosystem.
