Is there some group which collects funds for Bitcoin promotion? If some group like this can create advertisements for Bitcoin, more people can become aware. Such mediums should be targeted which have reach on audience that is still not familiar with crypto.
Those who are promoting BTC are also the consumers of it, and we are also consumers of BTC, so what different impact they will make that we cannot make? Will they convince people around you more than your own words? If you really wanted to promote BTC then make some banners and start teaching about BTC for free of cost also try to give them incentives like one of the members here tried to do.
And what do you mean by such mediums should be targeted? because there are many international and local mediums that are trying hard to promote BTC not because they like BTC so much, but just because they do know BTC can change their lives BTC can prevent a gambler from wasting his money on gambling and can move it to the BTC.
BTC has provided a new way for the poor to be rich in no time, it makes many millionaires and after doing some research I found these 2 platforms that can be considered as promotive companies for BTC but I prefer to do your own research.
