0 confirmation transactions already exist...it's been a thing since Bitcoin existed
Yes. I understand that.
the thing is, do you trust the transaction if it's not confirmed
That's the issue I have. No. I don't
EVER trust 0 confirmations. That's not how its supposed to work in Bitcorn.
I have had people trust 0 confirmation transactions from me. But for exterior reasons not related to the currency.
Such as buying a coffee and drinking it there at the small cafe where I chatted a bit with the owner already. Or a hamburger place.
Though I have had people trust larger transactions from me...but those were for localbitcoins after we had established a relationship and trust. With the full knowledge that if I screwed them over they could give me bad feedback and make further selling of bitcoins by me very difficult.
