I'm admittedly green when it comes to the day-to-day workings of Bitcoin but put some money into it on Coinbase a few weeks ago.
I decided to see how easy it was to use for transactions, so I bought $2 of credit with an online service. But the payment service this other company used charged a $6 fee of some kind, and there was also a $8 'transaction fee' for the Bitcoin itself, meaning it cost around $16 to get my $2 of credit :-D I decided I'd probably stick with it as an investment instead of a currency..
