The main bitcoin-related service can no longer be advertised on the forum, that for one thing.
I have never seen duelbits blackjack or monkey tilt in Facebook or Instagram ads. But I do see them here. Maybe they can't announce there? Legal restrictions? I don't know the exact reason, but that is a fact. I don't see them in social media.
That's right, I've seen Youtube videos where the influencer talks about Ledger or Trezor and has a referral code if you buy them with his link. If Ledger or Trezor don't advertise here it will be because they see more ROI doing it another way.
The case of bitcoin-related services that can't advertise here is already known.
Then we have casinos, which until recently could function as mixers but more and more have been introducing KYC and wagering requirements that prevent it. If they advertise here and not elsewhere it is partly because of legal restrictions and partly because they operate in limbo. They are in a transition phase, the moment they are forced to operate like any other fiat casino they will disappear from here too.
Bitcoin projects are mostly not "likeable" by Average Joe because people don't care with it's development. Even hardware wallet is a must for someone who own a good amount of Bitcoin, but the reality not many people want to buy hardware wallet, for them it's an unnecessary extra cost. This make them in loss since not many people want to buy hardware wallet.
If we're talking about centralized exchange, isn't most users here say to avoid centralized exchange?

Of course centralized exchange don't want to pay the user that talking bad against them instead of promoting.
That's right, this forum is pretty much anti-anything that can be advertised, anti-kyc exchanges, anti-kyc wallets, anti trezor and ledger for their attacks on privacy, and the OP is anti-casinos. So what do you want to be advertised here?
