where no third party has a hand and there is no chance of losing money.
I wouldn't go that far though. A lot of people have lost money getting their funds stolen one way or another.
Also, I'd like to know where you got this number:
Bitcoin is accepted by more than thirty thousand organizations around the world like WordPress, Microsoft, Wikipedia, Overstock.
The reason people have lost money is not due to security flaws within bitcoin network or payment system! People have lost money because of hacking incidents which can happen with your banking account as well. It doesn't have anything to do with bitcoin really! Bitcoin indeed is the most secure payment system in the world. There is no doubt about it!
For the second statement of OP, I think the number is imaginary. I am able to find a resource which says around 15 thousand business establishments accept bitcoin. Read below,
