hi , is there anything against selling my a8 pro licence if i won it ,instead of bought it ?

as i see it , i legally own it and may sell it , as long as i got it from conitec ,and did not buy/receive it from someone else who pre owned it .

is this correct?

if so , i would like to sell it , would anyone then be interested , and how do you guys usually do payment , do you prefer electronic transfer or paypal ?

greets.
