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
I think it is because the regulations of some countries, and the government doesn't support the ads of bitcoin.
The decentralized nature of bitcoin and cryptocurrency makes government cannot take the responsible if something happening in btc if they advertise it on their country. That's why we rarely or never see any bitcoin ads in media.
