Why we don't see advertisment about bitcoin technology and the diffrence between it and other payment systems , i know miners and traders who only know they can make money with btc but don't really know what is it or what it can be used for , we need some community driven ads all over the web to tell ppl what really btc and decentralized payments is to get real investors not just bumpers jumpers
Bitcoin already became popular, no need to advertise bitcoin anymore.
If you ask peoples in my country whether they know bitcoin or not, they mostly will say yes.
I think this is because the community of bitcoin has growing and making awareness to other peoples, not the ads of bitcoin.
