All origination expenses the asset owner has to pay in fiats. The exact amount of fees will depend on the asset class and smart contract details.
I did't get something right. I thought that all the costs would be exclusively in LAT.
It will definitely be, but not in the very near future. LAToken must show the success of their LAT as a means of payment to the general public, not just to crypto-currency fans, like us. I think it will be in three to five years maybe.
I think LATOKEN should show results much earlier, so as not to lose the trust of the community.
