When the seller accept the transaction he must have in hand a proof of the product delivery etc to make sure the buyer don't cheat on him. If this is a service he must proof that the service have been completed.
How will you ensure that the buyer receives the promised product?
That's a very interresting question. And I'm glad you asked. I don't know if it's like that in every countries but when you send a package for a product they will check the weight of the package and you can ask to write it in the box. Of course it still can be bypassed. With other site like ebay using paypal this still can be made, btw i'm working on this issue and if anyone have suggestion about it he's welcome .
I personally like crows, but a lot of people associate corvids with stealing. The thieving magpie and so on.
Definitely not an association you want to evoke if you want people to trust you with their money!
Perhaps you should choose a more innocuous bird to represent your brand.
BTChicken ? BTCrane ? BTCackling goose?
oh thanks for the suggestion I choose this name cause I was thinking it must be apropriated to use a related name. I'll think about it, thanks for the suggestion.
