Lol, people are in bitcoin because it's worth dollars. if it weren't there would be zero people in bitcoin besides those trying to get other people's dollars 

 That's how you get into it. But sooner or later one realises that dollars are just paper and bitcoin is the real money.  

 Lol, the only reason you can retire on bitcoin is through dollars. if bitcoin was worth zero dollars nobody would be investing.  

 I don't need dollars to buy goods and services. 

 Lol, yea right. Bitcoins market revolves around the dollar
