my investment
This is one of the big problems I see. Lots of people think Bitcoin is some kind of "investment scheme", it's not. Would you "invest" your money by depositing it into PayPal? Bitcoin is a replacement for PayPal. Use it just like you would PayPal. If you need to accept or send a payment to/from someone over the internet, then use bitcoin. Buying bitcoins to speculate on the value is gambling, not investing.
ps. I'm not blind, I was just speaking generally as I continually hear people refer to their bitcoin "investment".
Bitcoin IS an investment. It's the best investment in modern history. Comparing it with depositing to PayPal is outright silly since that's a loan to Ebay (paypal is a subsidiary to Ebay) while buying Bitcoin means owning a percentage of a limited commodity.
How can people not get this?
They do get it. All the bears and trolls who have crawled out of the woodwork bleating the end of the world (when it is obvious this move down has run out of steam) believe in bitcoin just as much as you. That's why they want your coins.
