Cool that you're posting this here, but I don't think this is the right place. Most people who come here already know the advantages of bitcoin.
You probably should post it on a 'regular' forum where people don't know about bitcoin. It's better to spread awareness there then here.
Telling your friends/family also works better than posting here.
I prefer bitcoin though I believe that cash is still necessary because bitcoin strikes it's high value for just a short period in time. By just keeping it, we can double the money that we have. Also, bitcoin transactions are easier and more convenient. Through bitcoin, we'll have the best and high profit that we may keep as our earnings for the future.
