They're not similar, and the relationship between the two is so obvious that only people scraping their claws on language barriers need to have it explained to them.

It drives me nuts when I read shitposts like "I join bitcoin because it gives a good income" or some ridiculous garbage like that.  Indeed, like OP is saying, such people are getting BTC (the cryptocurrency) confused with bitcointalk (the forum).  And the problem is, for a lot of people in 3rd world countries who heard about bitcointalk from friends, there is no difference between the two.  Bitcointalk IS bitcoin for them, and they see this forum as a job...which is another issue entirely.

Good thread, OP.  I'm going to hope that people actually read this and figure out the difference.
