Huh? Accepting BTC is 100% safe, unlike every other payment method.
How is it 100% safe?
You can lose a wallet over an inexperienced staff member.
Wait, which staff members do I trust with a currency that is anonymous?
Didn't some drug dealer just run off with 108 million dollars in bitcoins?
I call it about 5% safe.
you can't, you shouldn't even give the private key to your staff members, the public key is enough.
you only need the public key to accept payments.
in fact, your staff would be more likely to run off with a couple of dollar bills than he would be with bitcoins.
after all, dollar bills are as anonymous as bitcoins.
