It may be correct to make a separate table of old proven casinos.  And separate all the others into a second table.  Then it will be honorable to move the site from the second table to the first after enough time has passed.  It seems to me that it will be convenient for players who are not very well versed in the crypto casino gaming industry and do not read much reviews on reputable forums, such as, for example, our BTT. 
But these are just my thoughts and not at all an instruction for devs.
