* Payments cannot be reversed
Advantages.
uhh my experience:
I'm using bitcoin at least once every week for buying some product/service (for last ~3 years) and I really can't call "non-reverse payment" system as advantage. Quick example: I paid part of my BFL order with BTC and part with paypal.
With BTC, I never got my money back, with paypal I simply opened dispute and they pushed them to reverse everything. I also made lot of mistakes during usage of paypal last years (wrong amount, wrong mail address) and I never had any problems to fix them.
With BTC, in last years I sent them once incorrect address (wrong copy paste) and 2x made mistake with floating point..
If you think, that non-reverse payment system is advantageous for customers/end-users, please time to time turn off your laptop, go outside and ask common people, what they think. maybe you will be surprised..
That is true. Many people prefer the security the bank offers them, which is why they have their money there.
I am however sure that we will at some point see Bitcoin banks that will do that.
The question now is: Will merchants accept Bitcoin if they have to wait for 3 months for their payment to be cleared?
