Well the only bad thing around bitcoin is they havent support and chargeback option that would be something amazing to have ,but those dont affect bitcoin at all,with bitcoin being more safety you just need to confirm all details before make any payment.Bitcoin is sent instant and holds some minutes till the network make the transaction happen.
Why is it a bad thing that people can't do chargebacks with Bitcoin? I see no chargebacks as a huge plus!
That's also the main reason for some people to ditch PayPal and start using Bitcoin because they know when they receive the money in their wallet, that everything is fully theirs. No more worries about chargebacks.
