I guess even if we dont spread the news, bitcoin adoption is already inevitable seeing its all over the internet. Im not really into voicing out about bitcoin and all the positive things it has done for me, but rather Im more on showing them the proofs how bitcoin changed my life. But if they come to ask me about bitcoin, of course Id be very willing to answer them based on facts, including the risks involved when investing into bitcoin.
I think that's the best thing about bitcoin, you do not need to do marketing for it, you just do you and bitcoin will make your life better and when it does, people see it and people will think "this guy wasn't living this great, then he got into bitcoin, and now he lives great, maybe I should go into bitcoin as well" and that is the best marketing for bitcoin.
It makes your life better, depends on how you use it of course, there are idiots out there who put all their money into 100x leverage betting and losing and they are living a terrible life which gives bitcoin a bad name, but there are millions more who makes money from it and I can tell you that it's really a good thing.
