Creators can kick-start their comics without over-investing themselves, hurting their budget or risking ruining the reputation by having a comic release (mint).
With dReader presales feature creators are able to upload the concept art along with the plot description and thus survey the audience's in such a comic.
With minimum time dedication, creator can come to a strong conclusion if the comic idea they had is worth pursuing. On the other hand, early project supporters lose nothing if the presale fails since the project will be canceled and their funds returned from the Escrow wallet.
However, if the presale succeeds... no harm is done. Investors have a copy of the comic issue secured (and possibly bought by a cheaper price than the regular primary sale price). Creator can start the production risk-free and with peace of mind because of the fact that the comic is sentenced to success!
