Bitcoin does not work because people do not trust to buy things with bitcoin. I have a site running now for 5 months selling precious metals, made plenty of sales with credit card, bank transfer, no problems but not a single bitcoin purchase!
What is the point in bitcoin again?
Bitcoin works fine. Just because nobody is paying you via bitcoins isn't a problem with BTC. Maybe you're not promoting your site enough. How many people are using paypal on your site? Do you accept it? I'm guessing not since its so easy to do a chargeback but just because you don't trust it doesn't mean Paypal is broke.
