I think because Bitcoin really is something too vague , unrealistic . Even people who have knowledge of information technology are hard to understand let alone those who do not know anything about computers
Sure, but it is obvious that in the beginning it will be hard to understand how bitcoin works. As you,me and all the other users who have "heard" about bitcoin in the first days, no one know what bitcoin is really but each day we have learned the "background" (with a little IT knowledge) and now we can explain to the "newbie" how to buy/spend bitcoin easily (trust me, if you talk to a person "you can send thousand & thousand of dollars with only 0.03 $ of fee" they will start to use it for send money to their relatives/parents in other countries

, instead to use WU, moneygram or other money transmitter).
Yes, as i said above to Katsou and now to you. Sometime, I also don't understand what I said to my family. Hihihihi !;D
