Teenager would be the easiest generation to teach bitcoin to, you don't need to teach them the whole in's and out's just a bit about public/private key pairs, sending/receiving addresses and secure coin holding and they will pick up the rest very quickly.

bitcoin is a safe and well developed currency...and it is spread in all over the world...millions of poeple using bitcoins in there daily life..yes bitcoin have a bright future.

we can buy bitcoin from all over the world..online,from banks also..

you are right my brother...bitcion goes to high level..and the gold are remains constant..so bitcoin is much bitter than gold.
